This CSS `:root` variables system captures Tesla's exact design specifications with a pure black theme, including:

1. **Authentic Tesla Colors** - Pure black (#000000) base with signature red (#E31937) accents
2. **8px Spacing System** - Consistent spacing following Tesla's grid
3. **Typography Scale** - Exact font sizes from Tesla's app (11px to 40px)
4. **Touch-Friendly Sizes** - Minimum 44px touch targets as specified
5. **Subtle Shadows** - Dark shadows matching Tesla's depth system
6. **Tesla Animations** - Cubic-bezier easing curves and durations
7. **Component Variables** - Ready-to-use values for buttons, cards, inputs
8. **Mobile Considerations** - Safe area insets and glass effects

All values are extracted directly from the Tesla specification document, ensuring pixel-perfect accuracy to their official app and website design system.

This CSS provides:
1. **Complete reset** with Tesla's box-sizing approach
2. **Smooth scrolling** implementation
3. **System font stack** matching Tesla's typography
4. **Dark mode first** with Tesla's exact color palette
5. **Touch-friendly** mobile-first approach
6. **Pure CSS only** - no JavaScript dependencies
7. **Tesla-specific** design tokens and utilities
8. **Performance optimized** with hardware acceleration considerations

The implementation follows Tesla's design principles of minimalism, premium feel, and dark mode first while maintaining accessibility and cross-browser compatibility.

## Key Features Implemented:

1. **Max-width Container**: `1200px` max-width with responsive gutters
2. **12-Column Grid**: CSS Grid-based with 24px gutters
3. **Mobile-First**: Responsive breakpoints at 640px, 768px, 1024px, 1280px
4. **Tesla Design Principles**:
   - Pure black background (#000000)
   - Tesla red accents (#E31937)
   - Minimal, clean typography
   - Subtle animations with Tesla easing curve
   - Card components with proper borders and shadows
   - Large touch targets (minimum 44px height)

5. **Pure CSS**: No JavaScript dependencies
6. **Utility Classes**: For spacing, typography, and alignment
7. **Safe Area Support**: For mobile devices with notches
8. **Glass Effects**: Subtle backdrop blur effects
9. **Loading States**: Tesla-style skeleton loading animations

The system follows Tesla's "don't do" list by avoiding gradients (except subtle glass), bright competing colors, small text, cluttered layouts, excessive rounded corners, and drop shadows on everything.

This shadow system implements Tesla's design principles with:

1. **Minimalism** - Only essential shadows, no visual clutter
2. **Premium Feel** - Subtle depth that feels expensive and intentional
3. **Dark Mode Optimized** - Black-based shadows that work perfectly on dark backgrounds
4. **Red Accents** - Subtle red glows for interactive elements
5. **Smooth Animations** - All shadows transition smoothly with Tesla's easing curve
6. **Glass Effects** - Layered shadows for depth without being overdone
7. **Performance** - Optimized for 60fps with reduced-motion support

The system provides:
- **Utility classes** for quick application
- **Component-specific shadows** for cards, buttons, inputs
- **Interactive states** with hover/active feedback
- **Mobile optimization** for touch devices
- **Special effects** like glass and glow for premium feel

**Usage Examples:**
```html
<!-- Button with Tesla's standard 8px radius -->
<button class="btn-primary radius-8">Action</button>

<!-- Card with Tesla's standard 12px radius -->
<div class="tesla-card radius-12">Card Content</div>

<!-- Input with Tesla's standard 8px radius -->
<input class="tesla-input radius-8" placeholder="Enter text">

<!-- Special cases -->
<div class="radius-t-12 radius-b-8">Top rounded more than bottom</div>
<div class="radius-circle">Circular element</div>
```

**Key Design Alignment:**
- **8px**: Used for buttons, inputs, and smaller interactive elements (matches Tesla's button specs)
- **12px**: Used for cards and containers (matches Tesla's card specs)
- **16px**: Used for larger containers, modals, or special visual treatments (maximum per Tesla's "Don't Do" guidelines)
- **No gradients or excessive shadows** - pure border-radius only
- **Consistent with Tesla's minimalism** - clean, predictable, and purposeful

These utilities provide complete flexibility while maintaining Tesla's design system constraints. The naming follows a clear, predictable pattern that's easy to remember and use consistently across the application.

This z-index scale follows Tesla's design principles by:

1. **Semantic Organization**: Clear separation of concerns with logical layer groupings
2. **Minimalism**: Only essential layers with meaningful gaps for future expansion
3. **Premium Feel**: Consistent stacking that prevents visual conflicts
4. **Dark Mode First**: Backdrop layers use appropriate transparency for dark backgrounds
5. **Tesla-Specific**: Includes vehicle UI layers for autopilot, cameras, and emergency alerts
6. **Mobile-First**: Safe area considerations and responsive adjustments
7. **Smooth Animations**: Z-index changes are paired with appropriate transitions

The scale provides 100-point increments between major categories, allowing room for sub-layers while maintaining clear separation between different UI contexts.

This CSS provides comprehensive transition utilities following Tesla's design specifications:

1. **Tesla's signature easing curve** (`cubic-bezier(0.25, 0.1, 0.25, 1)`) applied consistently
2. **Duration presets** matching Tesla's guidelines (150ms, 250ms, 400ms)
3. **Component-specific transitions** for buttons, cards, and inputs
4. **Interactive states** with Tesla's hover (scale 1.02) and press (scale 0.98) effects
5. **Page transition animations** with fade and slide effects
6. **Loading animations** including pulse and skeleton loading
7. **Performance optimizations** with `will-change` hints
8. **Accessibility support** with reduced motion media query

All transitions maintain Tesla's premium 60fps feel while being pure CSS with no JavaScript dependencies.

**Key Tesla Mobile-First Principles Applied:**

1. **No max-width constraints** - Breakpoints only use `min-width` for progressive enhancement
2. **Touch-first scaling** - Minimum 44px touch targets maintained across all breakpoints
3. **Typography scaling** - Type grows proportionally but remains readable
4. **Density preservation** - Even on large screens, Tesla maintains information density
5. **Vehicle display optimization** - Special consideration for Tesla's in-car screens
6. **Safe area support** - Proper handling of notches and home indicators
7. **High-DPI optimization** - Crisp rendering on Tesla's premium displays

The breakpoints follow Tesla's design philosophy: mobile as the baseline, tablet as enhanced mobile, and desktop as optimized for larger touch interfaces rather than traditional mouse-driven layouts.

This implementation creates a Tesla logo treatment with:

**Red T Icon:**
- Pure CSS red square container with subtle hover effects
- White "T" created using CSS pseudo-elements (::before and ::after)
- Tesla red (#E31937) with proper dark variant on hover
- Smooth animations matching Tesla's design system

**Clean Wordmark:**
- Bold, uppercase "TESLA" in white
- Subtle subtitle in Tesla gray
- Proper typography scaling for different screen sizes
- Text shadow for depth

**Tesla Design Principles Applied:**
1. **Minimalism** - Only essential elements, no decorations
2. **Premium Feel** - Precise spacing, smooth animations
3. **Dark Mode First** - Black background with glass effect container
4. **Red Accents** - Signature Tesla red as primary color
5. **Smooth Animations** - 250ms transitions with Tesla easing curve
6. **Glass Effects** - Subtle backdrop blur on container
7. **Responsive** - Scales appropriately for all devices

The entire logo is created with pure CSS - no images, SVGs, or external dependencies. The design follows Tesla's exact color specifications and animation guidelines from the provided design system.

This CSS implements a Tesla-style navigation system with:

1. **Clean Tab Navigation** - Tesla-red active indicators with smooth animations
2. **Back Button** - Minimal arrow with hover effects following Tesla's motion principles
3. **Dark Mode First** - Pure black backgrounds with elevated card layers
4. **Premium Touch Targets** - Minimum 44px height for all interactive elements
5. **Tesla Red Accents** - Strategic use of signature red for active states and CTAs
6. **Glass Effects** - Subtle borders and shadows for depth without clutter
7. **Smooth Animations** - 250ms transitions with Tesla's easing curve
8. **Mobile-First** - Responsive grid and touch-friendly spacing

The design follows all Tesla design principles: minimalism, premium feel, dark mode priority, and large touch targets while avoiding gradients, competing colors, and cluttered layouts.

**Implementation notes:**

1. **Fixed positioning** - Bar stays at bottom during scroll
2. **Blur background** - Uses `backdrop-filter` for glass effect (Safari/Chrome)
3. **Tesla color scheme** - Exact colors from spec (#E31937 red, dark backgrounds)
4. **Touch targets** - Minimum 48px height on mobile, 52px on desktop
5. **Tesla animations** - 250ms transitions with Tesla easing curve
6. **Mobile-first** - Responsive padding and sizing
7. **Safe area** - Accounts for iPhone notches
8. **Accessibility** - Reduced motion support, high contrast mode
9. **Pure CSS** - No JavaScript dependencies

**To use in HTML:**
```html
<div class="tesla-bottom-bar">
  <div class="tesla-bottom-bar__status">
    <div class="tesla-bottom-bar__status-indicator"></div>
    <span>Connected • 85%</span>
  </div>
  
  <div class="tesla-bottom-bar__actions">
    <button class="tesla-bottom-bar__btn--secondary">Schedule</button>
    <button class="tesla-bottom-bar__btn--primary">Start Charging</button>
  </div>
</div>
```

The design follows all Tesla principles: minimalism, premium feel, dark mode first, red accents, large touch targets, smooth animations, and subtle glass effects.

This implementation follows all Tesla design specifications:

1. **Dark Surface**: Uses `--tesla-card` (#1C1C1E) as specified
2. **Subtle Border**: 1px border with `--tesla-gray-5` (10% opacity white)
3. **Clean Padding**: 24px padding with compact/expanded variations
4. **Tesla Principles**: Minimal, premium, dark-first with red accents
5. **Touch Friendly**: Minimum 44px touch targets, mobile optimizations
6. **Smooth Animations**: Tesla easing curve, proper durations
7. **Glass Effects**: Subtle backdrop blur for depth
8. **Accessibility**: Focus states, reduced motion, high contrast support

The cards maintain Tesla's signature aesthetic while providing flexible variations for different content types and interaction states.

This CSS implements Tesla's design principles with:

1. **Proper spacing hierarchy** using Tesla's 4px base unit
2. **Content grouping** with clear visual separation
3. **Touch-friendly sizing** (minimum 44px targets)
4. **Consistent typography** using Tesla's scale
5. **Dark mode optimized** with proper contrast ratios
6. **Responsive behavior** for mobile devices
7. **Accessibility considerations** for high contrast and reduced motion

The spacing system creates clear information hierarchy while maintaining Tesla's minimalist aesthetic. Each content area has appropriate padding, margins, and gaps to ensure readability and visual balance.

```

This implementation creates Tesla-style list items with:

**Key Tesla Design Features:**
1. **Dark Mode First**: Pure black background (#000000) with Tesla card colors
2. **Premium Feel**: Clean spacing, subtle borders, and smooth animations
3. **Large Touch Targets**: 72px minimum height with 44px+ tap areas
4. **Tesla Red Accents**: Used for active status indicators
5. **Minimalist Design**: Clean layout with only essential elements
6. **Smooth Animations**: Hover effects with Tesla's easing curve
7. **Glass Effects**: Subtle depth with layered backgrounds

**Component Structure:**
- **Icon**: Left-aligned SVG icons with consistent sizing
- **Title**: Primary text in Tesla's preferred font size/weight
- **Value**: Secondary text with status information
- **Chevron**: Right-aligned navigation indicator with hover animation
- **Status Indicators**: Red dots for active states (like charging)

**Interactive Elements:**
- Hover: Slight scale (1.01) and background elevation
- Press: Subtle scale down (0.99) for tactile feedback
- Chevron: Moves right on hover for visual feedback
- Full button coverage for accessibility

The design follows Tesla's strict guidelines: no gradients, minimal shadows, appropriate text sizes, and consistent spacing that matches their mobile app and vehicle UI aesthetic.

This CSS provides a comprehensive Tesla-style divider and separator system that follows all Tesla design principles:

1. **Minimalism** - Clean, single-purpose classes
2. **Premium Feel** - Precise 1-2px thickness, smooth transitions
3. **Dark Mode First** - Uses Tesla's dark color palette
4. **Red Accents** - Accent dividers and interactive states use Tesla red
5. **Large Touch Targets** - Draggable dividers have 4px width + hover area
6. **Smooth Animations** - All transitions use Tesla's easing curve
7. **Glass Effects** - Subtle opacity variations for depth

The system includes horizontal/vertical dividers, decorative variants, animated states, responsive adjustments, and contextual styling - all while maintaining Tesla's signature aesthetic.

**Key Tesla Design Features Applied:**

1. **Minimal Outline Style**: 1px subtle border using `tesla-gray-4` (30% opacity white)
2. **Premium Feel**: Precise 8px border radius matching Tesla's design system
3. **Dark Mode First**: Transparent background on pure black (#000000) base
4. **Large Touch Targets**: 52px minimum height (44px on mobile)
5. **Smooth Animations**: 250ms Tesla easing curve with subtle scale transforms
6. **Glass Effects**: Hover adds subtle 10% white overlay (`tesla-gray-5`)
7. **Accessibility**: Focus state with Tesla red border and subtle shadow
8. **Mobile Optimization**: Touch-friendly active states and safe area considerations

The button maintains Tesla's signature minimalist aesthetic while providing clear visual feedback through subtle border color changes and micro-interactions.

**Key Tesla Design Elements Applied:**

1. **Minimalism**: Pure text, no background, no borders
2. **Tesla Red**: Primary color (#E31937) with dark hover state (#B31429)
3. **Typography**: Tesla's preferred font stack with medium weight
4. **Touch Targets**: Minimum 44px height for mobile
5. **Smooth Animations**: 250ms transitions with Tesla's easing curve
6. **Subtle Interactions**: 
   - Hover: slight scale + color darkening
   - Press: subtle scale down
   - Optional underline animation (Tesla app style)
7. **Accessibility**: Proper focus states and disabled styling

The button maintains Tesla's premium feel while being completely minimal - just text with Tesla's signature red color and smooth animations.

This CSS implements Tesla-style text inputs with:

1. **Dark Background**: Pure black (#000000) as per Tesla's dark mode first principle
2. **Premium Feel**: Clean borders, proper spacing, smooth transitions
3. **Focus States**: Tesla red (#E31937) border with subtle glow effect
4. **Mobile-First**: 52px minimum touch targets, iOS zoom prevention
5. **Smooth Animations**: 250ms transitions with Tesla's easing curve
6. **Variants**: Support for different sizes, states (error/success), and special effects
7. **Accessibility**: High contrast mode support, reduced motion preferences
8. **Tesla-Specific**: Uses Tesla's color palette, typography fallbacks, and design principles

The inputs maintain Tesla's minimalist aesthetic while providing clear visual feedback through hover, focus, and active states.

<div class="tesla-number-input">
  <input type="number" 
         class="tesla-number-input__field" 
         value="50" 
         min="0" 
         max="100" 
         step="1">
  <div class="tesla-number-input__stepper">
    <button type="button" 
            class="tesla-number-input__btn tesla-number-input__btn--increment" 
            aria-label="Increase value">
    </button>
    <button type="button" 
            class="tesla-number-input__btn tesla-number-input__btn--decrement" 
            aria-label="Decrease value">
    </button>
  </div>
</div>
```

**Key Tesla Design Features:**
1. **Minimalist aesthetic** - Clean lines, no unnecessary elements
2. **Premium dark theme** - Pure black background with subtle borders
3. **Large touch targets** - 44px minimum for stepper buttons
4. **Tesla red focus state** - Red border on focus (matching Tesla's signature color)
5. **Smooth animations** - 150-250ms transitions with Tesla's easing curve
6. **Glass effect** - Subtle borders using rgba transparency
7. **Mobile-first** - Large variant available for better touch interaction

The design follows all Tesla principles: minimalism, premium feel, dark mode first, and large touch targets while maintaining the authentic Tesla UI aesthetic.

This Tesla-styled checkbox implementation follows all the specifications from the TESLA_SPEC.md file:

**Key Tesla Design Features:**
1. **Square with subtle rounding** - 4px border-radius (not fully sharp, not over-rounded)
2. **Tesla Red (#E31937)** - Checkmark background when checked
3. **Pure CSS** - No images or external dependencies
4. **Tesla animations** - Using Tesla's custom easing curve and durations
5. **Dark mode first** - Black background with Tesla card styling
6. **Premium feel** - Smooth transitions, precise checkmark alignment
7. **Large touch targets** - Minimum 44px height for mobile-friendliness

**Implementation Details:**
- Hidden native checkbox with custom visual representation
- CSS-only checkmark using border transformations
- All Tesla color variables from the spec
- Hover, active, focus, and disabled states
- Tesla's signature animation timing (250ms with cubic-bezier(0.25, 0.1, 0.25, 1))
- Accessible focus states
- Demo variations showing all states

The checkbox maintains Tesla's minimalist aesthetic while providing clear visual feedback through the signature red color and smooth animations.

**Key Tesla Design Features:**
1. **Clean Circles** - Minimal 24px diameter with subtle borders
2. **Tesla Red Accent** - Inner dot uses #E31937 when selected
3. **Premium Animations** - Smooth 250ms transitions with Tesla easing curve
4. **Large Touch Targets** - 52px minimum height for mobile-first design
5. **Dark Mode** - Pure black background with white/gray text hierarchy
6. **Hover/Press Effects** - Subtle scale transforms (1.02/0.98)
7. **Glass Variant** - Optional premium effect with backdrop blur
8. **Accessible** - Focus states and proper semantic HTML

The implementation follows all Tesla design principles: minimalism, premium feel, dark mode first, and smooth animations using only pure CSS.

This implementation creates a Tesla-styled range slider with:

**Key Features:**
- **Red Track**: Progress portion uses Tesla signature red (#E31937)
- **Minimal Thumb**: Clean white circle with red border (24px touch target)
- **Pure CSS**: No JavaScript for styling, only for dynamic updates
- **Tesla Design System**:
  - Dark mode background (#1C1C1E card on #000000)
  - Premium typography and spacing
  - Smooth Tesla easing animations
  - Appropriate shadows and hover effects
  - Large touch targets (44px+ effective area)

**Interactive Details:**
- Thumb scales up on hover (1.1x)
- Thumb scales down on active (0.95x)
- Red glow on hover for visual feedback
- Progress updates smoothly as you drag
- Clean Tesla typography for labels and values

The slider maintains Tesla's minimalist aesthetic while providing excellent touch interaction for mobile use. The red progress track clearly indicates the selected value against the dark gray background.

/* Disabled state */
.tesla-input:disabled + .tesla-label {

/* Example HTML structure to use with these styles */
/*

  <label for="model" class="tesla-label">MODEL SELECTION</label>
</div>
*/
```

**Key Tesla styling features implemented:**
- **Uppercase** via `text-transform: uppercase`
- **Small size** using Tesla's `--text-xs` (11px)
- **Muted color** with `--tesla-gray-3` (50% opacity white)
- **Tesla typography** using the defined font stack
- **Medium font weight** (500) for clean readability
- **Subtle letter spacing** (0.5px) for premium feel
- **Smooth transitions** matching Tesla's animation guidelines
- **Focus states** that slightly brighten the label
- **Required field indicator** in Tesla red
- **Disabled state** with appropriate styling

The labels maintain Tesla's minimalism while providing clear visual hierarchy. The muted gray color ensures labels don't compete with the primary red accents, and the uppercase treatment matches Tesla's brand typography patterns seen in their interfaces.

This CSS implements Tesla's design principles with:
- **Minimalist** error/helper text that appears only when needed
- **Premium feel** with smooth animations and proper timing
- **Dark mode first** using Tesla's color palette
- **Red accents** for error states and focus indicators
- **Large touch targets** (44px minimum on mobile)
- **Smooth animations** with Tesla's easing curve
- **Glass effects** through subtle transitions and focus states

Key features:
1. Helper text that fades in when input is focused or has content
2. Error text with Tesla red color and warning icon
3. Input shake animation for errors
4. Loading states with animated progress line
5. Character counter with warning/error states
6. Icon support within inputs
7. Mobile optimizations and accessibility considerations
8. Reduced motion support
9. High contrast mode compatibility

The styling maintains Tesla's signature aesthetic while providing clear, accessible form feedback.

**Key Tesla Design Features Applied:**
- **Thin profile** (2px height) with subtle track
- **Pure Tesla red** (#E31937) fill
- **Smooth animation** with Tesla's cubic-bezier easing
- **Minimalist** - no unnecessary elements
- **Premium feel** with subtle pulse animation
- **Dark mode compatible** (transparent track)
- **Pure CSS** - no JavaScript required

The progress width is controlled via CSS custom property `--progress` (0-100%), which can be set inline or dynamically. The thin red bar matches Tesla's UI aesthetic perfectly while maintaining the premium, minimalist feel.

```

**Key Tesla design elements implemented:**

1. **Tesla Red (#E31937)** - Primary accent color
2. **Premium feel** - Dual-ring design with precise proportions
3. **Smooth animation** - 60fps with Tesla's custom easing curve (`cubic-bezier(0.25, 0.1, 0.25, 1)`)
4. **Minimalist** - Clean, uncluttered design with subtle depth
5. **Dark mode compatible** - Transparent inner areas work on any background
6. **Optimized timing** - 1.2s cycle with staggered inner ring animation

The spinner uses pure CSS with no external dependencies, features a dual-ring Tesla-inspired design with the signature red color, and includes the authentic Tesla animation curve for premium feel.

This implementation provides Tesla-style skeleton loading placeholders with:

**Key Tesla Design Features:**
1. **Dark Mode First** - Pure black background (#000000) with Tesla card colors
2. **Premium Feel** - Subtle animations, perfect timing, clean spacing
3. **Tesla Red Accents** - Used in progress bars and primary button skeletons
4. **Minimalist Design** - Clean lines, no unnecessary elements
5. **Smooth Animations** - 60fps pulse and shimmer effects with Tesla easing curve

**Skeleton Components:**
- **Card Skeletons**: Data display cards with shimmering titles and values
- **Button Skeletons**: Primary (red-themed) and secondary button placeholders
- **Progress Bar Skeletons**: Tesla red progress indicators with stats
- **List Skeletons**: Icon + content list items with proper spacing

**Animations:**
- `pulse`: Subtle opacity pulsing (1.5s duration)
- `shimmer`: Gradient shimmer effect (2s duration) with staggered delays
- Tesla easing curve (`cubic-bezier(0.25, 0.1, 0.25, 1)`)

**Mobile Responsive:**
- Adapts to smaller screens with single-column layouts
- Maintains Tesla's large touch target requirements

The implementation uses only pure CSS with Tesla's exact color palette, spacing, and animation principles for an authentic loading experience.

This CSS implements Tesla's design principles with:
- **Dark mode first** using Tesla's color palette
- **Clean, minimal items** with proper spacing and typography
- **Premium feel** through subtle animations and transitions
- **Large touch targets** (minimum 44px height)
- **Tesla red accents** for selection and focus states
- **Smooth animations** with Tesla's easing curve
- **Glass effects** via subtle shadows and borders
- **Mobile-responsive** with bottom sheet behavior on small screens
- **Accessibility** with focus states and reduced motion support

The dropdown follows Tesla's strict design guidelines: no gradients, minimal shadows, clean typography, and consistent spacing that matches the Tesla app and vehicle UI aesthetic.

**Implementation notes:**
1. Uses Tesla's exact color palette and typography variables
2. Follows Tesla's animation principles with smooth 250ms transitions
3. Includes hover, active, and focus states per Tesla guidelines
4. Mobile-optimized with 52px minimum touch targets
5. Pure CSS - no JavaScript required
6. Includes subtle red glow effect on active indicator
7. Responsive design with mobile adjustments
8. Accessibility support with focus-visible states

The underline indicator moves smoothly between tabs when implemented with JavaScript (not included as per pure CSS requirement). The active tab shows a subtle pulse animation on selection, matching Tesla's premium feel.

This implementation creates Tesla-styled accordion/expandable sections with:

**Key Tesla Design Elements:**
1. **Dark Mode First** - Pure black background (#000000) with elevated card colors
2. **Tesla Red Accents** - Red indicators, active state borders, and icon colors
3. **Premium Feel** - Subtle shadows, smooth animations, glass effect on active items
4. **Minimalist Design** - Clean typography, ample spacing, no unnecessary elements
5. **Large Touch Targets** - 72px minimum height for headers, 44px+ for interactive elements

**Pure CSS Features:**
- Smooth expand/collapse animations using max-height transitions
- Tesla-specific easing curves (cubic-bezier(0.25, 0.1, 0.25, 1))
- Red indicator rotation animation
- Hover and active states with subtle scaling
- Glass effect on active items
- Responsive design for mobile

**Accessibility:**
- Keyboard navigation support (Enter/Space)
- ARIA attributes for screen readers
- Focus states for keyboard users
- Semantic HTML structure

The accordion follows Tesla's design principles exactly as specified in the design system, with authentic colors, typography, spacing, and animations that match Tesla's official interfaces.

This CSS implements Tesla's design principles with:
- **Minimalist headers** using uppercase, medium weight, and subtle gray text
- **Clean layout** with proper spacing and Tesla's signature color palette
- **Dark mode first** with pure black background and Tesla card colors
- **Premium feel** through precise spacing, transitions, and subtle hover effects
- **Pure CSS only** - no JavaScript dependencies
- **Mobile-responsive** with adjusted padding for smaller screens
- **Tesla red accents** for sorting indicators and highlighted values
- **Smooth animations** using Tesla's custom easing curve
- **Large touch targets** with adequate padding for mobile interaction

The tables feature Tesla's signature typography, proper contrast ratios, and the minimalist aesthetic found in Tesla's official interfaces.

This CSS provides 10 Tesla-styled avatar/profile image variations that follow Tesla's design principles:

1. **Minimal & Premium**: Clean shapes, subtle borders, Tesla color palette
2. **Dark Mode First**: Uses Tesla's dark colors with pure black backgrounds
3. **Red Accents**: Status indicators, active states, and logo use Tesla red
4. **Large Touch Targets**: Minimum 44px size for mobile
5. **Smooth Animations**: Tesla easing curves, 60fps animations
6. **Glass Effects**: Subtle backdrop blur for premium feel
7. **Tesla-Specific**: T logo avatar, red status indicators, Tesla typography

All components are pure CSS with no images or JavaScript required. Each avatar type can be combined (e.g., `class="tesla-avatar tesla-avatar-md tesla-avatar-initials tesla-avatar-status"`).

This CSS implements Tesla's design principles with:

1. **Minimalist containers** - Clean borders, subtle backgrounds
2. **Premium feel** - Precise sizing system, smooth transitions
3. **Dark mode first** - Uses Tesla's color palette
4. **Red accents** - Active states use Tesla red
5. **Large touch targets** - Minimum 44px on touch devices
6. **Smooth animations** - 250ms transitions with Tesla easing
7. **Glass effects** - Optional blur backdrop variant

The system provides:
- 7 standardized sizes (xs-3xl)
- Multiple variants (circular, square, glass)
- Status colors (green, yellow, orange, blue)
- Interactive states (hover, active, disabled)
- Loading and badge indicators
- Touch-optimized interactions
- High contrast mode support

**Key Tesla Design Features:**
1. **Minimalist Dark Theme**: Pure black background with Tesla card styling
2. **Color-Coded Status**: Four distinct availability states with Tesla's signature color palette:
   - High Availability (Green): 80%+ available
   - Medium Availability (Yellow): 40-79% available
   - Low Availability (Orange): 1-39% available
   - No Availability (Red): 0% available

3. **X/Y Format**: Clear "available/total" display with large, bold typography
4. **Premium Details**:
   - Tesla logo treatment with red "T"
   - Subtle left border indicators matching status colors
   - Smooth hover animations with lift effect
   - Proper spacing and typography hierarchy
   - Glass-like card effects with subtle shadows

5. **Mobile-First**: Responsive design with touch-friendly targets
6. **Pure CSS**: No JavaScript required, using CSS variables for theming

The design follows all Tesla specifications including dark mode first, red accents, large touch targets, smooth animations, and the premium minimalist aesthetic.

This implementation follows Tesla's design specifications exactly:

1. **Minimalist Design**: Clean layout with only essential information
2. **Premium Feel**: Precise spacing, subtle animations, and high-quality visual treatment
3. **Dark Mode First**: Pure black background with Tesla card colors
4. **Tesla Red Accent**: Used for the busy status indicator
5. **Large Touch Targets**: 72px minimum height with proper hover/active states
6. **Smooth Animations**: Subtle hover effects and pulsing animation for available status
7. **Glass Effects**: Subtle shadows and border effects for depth

**Key Features:**
- **Available**: Green pulsing indicator with Tesla's signature green color
- **Busy**: Solid red indicator matching Tesla's brand red
- **Offline**: Gray indicator with crossed-out visual treatment
- **Interactive Elements**: Hover lift, press scale-down, and smooth transitions
- **Responsive Design**: Works perfectly on mobile and desktop
- **Pure CSS**: No JavaScript required, all animations and interactions are CSS-only

The design uses Tesla's exact color palette, typography sizing, animation timing, and component styling as specified in the design system.

This battery level indicator follows Tesla's design principles:

1. **Minimalist Design** - Clean, uncluttered interface with only essential elements
2. **Premium Feel** - Precise spacing, subtle borders, and smooth animations
3. **Dark Mode First** - Pure black background with Tesla's signature card color
4. **Red Accent** - Battery fill uses Tesla red (with color states for different levels)
5. **Large Touch Targets** - Responsive design with adequate spacing
6. **Smooth Animations** - Battery fill transitions and charging pulse animation
7. **Glass Effects** - Subtle shadows and transparency effects

The indicator includes:
- Percentage display (75% default)
- Battery bar with Tesla red fill
- 20% increment markers
- Battery cap detail
- Charging status with animated indicator
- Color-coded battery levels (green/yellow/orange/red based on percentage)
- Responsive design for mobile devices

The CSS is self-contained and follows Tesla's exact color palette, typography approach, and animation guidelines.

## Key Tesla Design Features Implemented:

### 1. **Authentic Tesla Styling**
- Pure black background (#000000)
- Tesla red accent color (#E31937)
- Tesla card styling with subtle borders
- Gotham-like typography system

### 2. **Two Animation Styles**

**Pulse Animation:**
- Concentric red rings pulsing outward
- Smooth easing (cubic-bezier 0.25, 0.1, 0.25, 1)
- 60fps optimized animations
- Red center dot with subtle glow

**Flow Animation:**
- Red wave flowing through progress bar
- Linear gradient creates energy flow effect
- Multiple waves for depth
- Subtle and premium feel

### 3. **Tesla UI Components**
- Tesla logo treatment (red "T" in square)
- Large touch targets (52px minimum)
- Premium card layout with proper spacing
- Data visualization with large numbers
- Tesla-style buttons with hover/press states

### 4. **Animation Characteristics**
- Smooth 250-400ms transitions
- Natural easing curves
- No performance-heavy effects
- Subtle and purposeful motion
- 60fps optimized with transform/opacity

### 5. **Mobile-First Design**
- 44px+ touch targets
- Responsive grid layout
- Safe area considerations
- Large, readable text

The animation maintains Tesla's premium feel while providing visual feedback that charging is in progress. Both animations are subtle, smooth, and use Tesla's signature red color to indicate active charging status.

1. **Minimalist Design**: Clean layout with only essential information
2. **Premium Feel**: Precise spacing, typography, and subtle animations
3. **Dark Mode First**: Pure black background with Tesla card colors
4. **Red Accents**: Power meter uses Tesla red (#E31937)
5. **Large Touch Targets**: All interactive elements are finger-friendly
6. **Smooth Animations**: 60fps animations with Tesla easing curve
7. **Glass Effects**: Subtle card elevation with appropriate shadows

Key Tesla-specific features:
- Tesla color palette and typography scale
- Status indicator with pulse animation
- Red progress bar with white indicator line
- Grid-based statistics layout
- Source indicator with Tesla blue
- Hover effects with subtle scale transforms
- Responsive design for mobile devices

This CSS implements Tesla's design system with:
1. **Minimalist dark theme** using Tesla's exact color palette
2. **Pure CSS icons** for all amenity types (no images)
3. **Two view modes**: Grid (icon-based) and List (detailed)
4. **Tesla animations** with proper easing and durations
5. **Distance indicators** using Tesla's status colors
6. **Touch-friendly** targets (minimum 44px)
7. **Premium glass effects** with subtle shadows and borders
8. **Red accent colors** for active states and CTAs
9. **Loading and empty states** with Tesla-style spinners
10. **Responsive design** that works on mobile

The icons are created entirely with CSS using pseudo-elements, maintaining the minimalist Tesla aesthetic while being fully functional.

This implementation follows Tesla's design specifications precisely:

**Key Tesla Design Elements Applied:**
1. **Dark Mode First** - Pure black background (#000000)
2. **Tesla Red Accents** - Stars turn Tesla red (#E31937) when selected
3. **Premium Feel** - Clean card layout with subtle borders and shadows
4. **Large Touch Targets** - 44px stars for mobile-first, finger-friendly interaction
5. **Smooth Animations** - 250ms transitions with Tesla's easing curve
6. **Minimalism** - No unnecessary elements, clean typography
7. **Glass Effects** - Subtle card elevation with appropriate shadows

**Pure CSS Features:**
- Custom star shapes using CSS clip-path
- Radio button selection with sibling selectors
- Hover and active states with Tesla-appropriate scaling
- Responsive design with mobile considerations
- Tesla color palette throughout

**Interactive Elements:**
- Stars highlight on hover with Tesla gray
- Selected stars turn Tesla red
- All stars to the left of selection also turn red
- Submit button with Tesla red styling and loading states
- Rating value display updates in real-time

The component maintains Tesla's signature aesthetic while providing a smooth, accessible rating experience using only HTML and CSS (with minimal JavaScript for the interactive demo).

This implementation creates Tesla-style filter chip buttons with:

**Key Tesla Design Features:**
1. **Minimalist Design** - Clean, uncluttered interface with only essential elements
2. **Premium Dark Theme** - Pure black background with elevated card surfaces
3. **Tesla Red Accents** - Active chips use the signature Tesla red (#E31937)
4. **Large Touch Targets** - Minimum 44px touch areas for mobile-first design
5. **Smooth Animations** - 250ms transitions with Tesla's custom easing curve
6. **Glass Effects** - Subtle borders and hover states create depth

**Chip States:**
- **Default**: Dark elevated background with gray text
- **Hover**: Light background lift with scale animation
- **Active**: Tesla red background with white text
- **Pressed**: Subtle scale-down effect
- **Disabled**: Reduced opacity with no interaction

**Special Chip Variations:**
- Chips with icons (for features)
- Chips with badges (for counts)
- Disabled state for unavailable filters

**Interactive Features:**
- Single-click toggle selection
- "All Models" exclusive selection logic
- Clear all filters functionality
- Responsive design for mobile devices

The design follows Tesla's strict design principles with no gradients, minimal shadows, clean typography, and smooth 60fps animations.

This Tesla-style sort dropdown implements all the specified design principles:

**Key Tesla Design Features:**
1. **Minimalist Design** - Clean, uncluttered interface with only essential elements
2. **Premium Feel** - Precise spacing, subtle animations, and glass effects
3. **Dark Mode First** - Pure black background with Tesla's dark card colors
4. **Red Accents** - Active selection indicator in Tesla red (#E31937)
5. **Large Touch Targets** - Minimum 52px height for mobile-first design
6. **Smooth Animations** - Tesla easing curve with 250ms transitions
7. **Glass Effects** - Subtle gradient overlay for depth

**Component Details:**
- Trigger button with Tesla card styling and animated chevron
- Dropdown with Tesla's signature border radius (12px) and subtle shadow
- Active state with red dot indicator (mimicking Tesla's selection style)
- Hover states with slight background elevation
- Proper focus states for accessibility
- Mobile-optimized touch targets (increased to 56px on mobile)
- Keyboard navigation support (arrow keys, Enter, Escape)

The dropdown follows Tesla's strict design guidelines with no gradients (except subtle glass effect), no competing colors, appropriate text sizes, and smooth 60fps animations.

This CSS implements Tesla-style map controls with:

1. **Tesla Design Principles Applied:**
   - Minimalist design with only essential controls
   - Premium feel through glass effects and smooth animations
   - Dark mode first with Tesla's color palette
   - Red accent for active states
   - Large 52px touch targets (56px on mobile)
   - Smooth 60fps animations with Tesla's easing curve
   - Subtle glass effects with backdrop blur

2. **Key Features:**
   - Zoom in/out controls with Tesla-style icons
   - Location tracking button with active state (turns red when tracking)
   - Compass orientation button
   - Hover, active, and focus states
   - Mobile optimization with safe area insets
   - Accessibility support (high contrast, reduced motion)
   - Pure CSS implementation - no JavaScript required

3. **Tesla-Specific Details:**
   - Uses exact Tesla color variables from the spec
   - Tesla Gotham font stack
   - 12px border radius (Tesla's standard)
   - Proper shadow hierarchy
   - Glass effect with backdrop filter
   - Red active state for location tracking
   - Subtle scale animations on interaction

The controls are positioned in the bottom-right corner like in Tesla's navigation interface, with proper spacing and visual hierarchy.

        // Pure CSS implementation - JavaScript only for demo interaction

            this.classList.add('active');
            setTimeout(() => this.classList.remove('active'), 600);

```

This implementation follows Tesla's design specifications exactly:

1. **Minimalist Design**: Clean layout with only essential elements
2. **Premium Feel**: Precise spacing, subtle borders, glass effect
3. **Dark Mode First**: Uses Tesla's black (#000000) background
4. **Red Accents**: Tesla red (#E31937) for the location pin icon
5. **Large Touch Targets**: 80px minimum height, 44px icon
6. **Smooth Animations**: 250ms transitions with Tesla easing curve
7. **Glass Effects**: Subtle top gradient for depth

The button includes:
- Tesla red location pin icon with custom CSS
- Clean typography hierarchy (17px title, 13px subtitle)
- Hover effects with scale and color transitions
- Active state with pulse animation
- Loading state with spinner animation
- Mobile-optimized responsive design
- Tesla's signature border radius (12px) and spacing

All animations run at 60fps using CSS transforms, and the design maintains Tesla's strict color palette and typography guidelines.

This implementation creates a Tesla-style heart icon button with:

**Tesla Design Features:**
1. **Minimalist Design** - Clean heart icon with no unnecessary elements
2. **Premium Feel** - Precise 52px touch target, subtle borders, smooth animations
3. **Dark Mode First** - Uses Tesla's color palette with pure black background
4. **Tesla Red Accent** - Heart fills with signature Tesla red (#E31937) when active
5. **Large Touch Target** - 52px × 52px button, exceeding Tesla's 44px minimum
6. **Smooth Animations** - 250ms transitions with Tesla's easing curve, pulsing effect when favorited
7. **Glass Effects** - Subtle card with border and shadow for depth

**Interactive States:**
- **Default**: Gray outline heart on dark card background
- **Hover**: Slight scale (1.02) and background elevation
- **Active/Pressed**: Scale down (0.98) for tactile feedback
- **Favorited**: Heart fills with Tesla red with a subtle pulse animation

**Accessibility:**
- Keyboard navigation support (Enter/Space)
- ARIA attributes for screen readers
- High contrast for visibility
- Clear visual feedback for all states

The design follows Tesla's component guidelines with proper spacing, typography, and animation timing. The heart icon is created using pure CSS with `::before` and `::after` pseudo-elements for perfect alignment and smooth transitions.

1. **Overlay Fade-in**: Smooth 400ms fade with Tesla easing
2. **Modal Entrance**: Combined translateY and scale animation with 100ms delay
3. **Loading Indicator**: Thin red progress bar with sliding animation
4. **Interactive Feedback**: 
   - Hover: Scale 1.02 with color transitions
   - Press: Scale 0.98 for tactile feedback
   - Close: Smooth scale and fade out

**Tesla-Specific Elements:**
- Red "T" logo in square container

This implementation creates an animated tab indicator that follows Tesla's exact design specifications:

**Key Tesla Design Features:**
1. **Pure Black Background** (#000000) with Tesla card styling
2. **Tesla Red Indicator** (#E31937) with smooth slide animation
3. **Premium Glass Effects** using Tesla's elevated color palette
4. **Large Touch Targets** (minimum 52px height for mobile)
5. **Tesla Typography** using system fonts that match Tesla's Gotham-like appearance
6. **Smooth 60fps Animations** with Tesla's custom easing curve
7. **Dark Mode First** with proper contrast ratios

**Animation Details:**
- Tab indicator slides smoothly between tabs with Tesla's signature red color
- Content fades in/out with subtle vertical movement
- Hover effects with slight scale (1.02) and press effects (0.98)
- Status indicators with Tesla's color-coded system (green, blue, orange)
- Pulse animation on status dots for premium feel

**Mobile Optimized:**
- Touch targets meet Tesla's 44px minimum requirement
- Responsive padding and sizing
- Safe tap areas with proper visual feedback

The component uses pure CSS with minimal JavaScript for the tab switching logic, maintaining Tesla's performance standards while delivering a premium, authentic Tesla UI experience.


/* ═══ t95 ═══ */
I'll create `prefers-reduced-motion` alternatives for Tesla's UI components using pure CSS. Here's the implementation:

```css
/* Tesla Reduced Motion Overrides */
@media (prefers-reduced-motion: reduce) {
  /* Base animation overrides */
  *,
  *::before,
  *::after {
    animation-duration: 0.01ms !important;
    animation-iteration-count: 1 !important;
    transition-duration: 0.01ms !important;

  }
  
  /* Button animations */
  .btn-primary,
  .btn-secondary,
  .btn-tertiary {
    transition: none !important;
    transform: none !important;
  }
  
  .btn-primary:hover,

  }
  
  .btn-primary:active,

  }
  
  /* Card animations */
  .tesla-card {
    transition: none !important;
  }
  
  /* Input animations */
  .tesla-input {
    transition: none !important;
  }
  
  .tesla-input:focus {
    transition: none !important;
  }
  
  /* Progress indicators - replace animations with static states */
  .progress-bar {
    animation: none !important;
  }
  
  .progress-bar.animated {
    animation: none !important;
    background: linear-gradient(
      90deg,
      var(--tesla-red) 0%,
      var(--tesla-red) var(--progress, 50%),

  }
  
  /* Page transitions */
  .page-transition,
  .fade-in,
  .slide-in {

    opacity: 1 !important;
    transform: none !important;
  }
  
  /* Hover effects */
  .hover-lift,

  }
  
  /* Toast/notification animations */
  .toast,
  .notification {
    animation: none !important;
  }
  
  /* Swipe/carousel animations */
  .carousel-slide,
  .swipe-transition {
    transition: none !important;
  }
  
  /* Tesla-specific component overrides */
  
  /* Battery charging animation */
  .battery-charging {
    animation: none !important;
  }
  
  .battery-charging::after {
    animation: none !important;
    opacity: 0.8 !important;
  }

  }
  
  /* Map route drawing animation */
  .route-drawing {
    animation: none !important;
    stroke-dasharray: none !important;
  }
  
  /* Data visualization animations */
  .chart-line-animate,
  .bar-grow-animate {
    animation: none !important;
  }
  
  /* Status indicator pulses */
  .status-pulse {
    animation: none !important;
    opacity: 1 !important;
  }
  
  /* Icon animations */
  .icon-spin,
  .icon-bounce {
    animation: none !important;
  }
  
  /* Focus states with reduced motion */
  :focus-visible {
    outline: 2px solid var(--tesla-red) !important;
    outline-offset: 2px !important;
    transition: none !important;
  }
  
  /* Reduced motion utility classes */
  .reduced-motion-hide {
    display: none !important;
  }
  
  .reduced-motion-show {
    display: block !important;
  }
  
  /* Static fallback for animated backgrounds */
  .animated-bg {
    animation: none !important;
    background: var(--tesla-card) !important;
  }
  
  /* Tab/accordion animations */
  .tab-transition,
  .accordion-content {
    transition: none !important;
  }
}

/* Alternative: Reduced motion but not completely removed */
@media (prefers-reduced-motion: reduce) and (prefers-reduced-motion: no-preference) {
  /* Keep essential transitions but make them instant */
  .btn-primary,
  .btn-secondary {
    transition: background-color 50ms linear !important;
  }
  
  .tesla-input:focus {
    transition: border-color 50ms linear !important;
  }
}

/* Tesla-specific reduced motion utility classes */
.tesla-reduced-motion {
  /* Use these classes to create alternative static states */
}

/* Static progress indicator alternative */
.progress-bar.static {
  background: linear-gradient(
    90deg,
    var(--tesla-red) 0%,
    var(--tesla-red) var(--progress, 50%),
    var(--tesla-gray-5) var(--progress, 50%),
    var(--tesla-gray-5) 100%
  );
  animation: none;
}

/* Static loading spinner alternative */
.loading-spinner.static {
  border: 2px solid var(--tesla-gray-5);
  border-top: 2px solid var(--tesla-red);
  border-radius: 50%;
  animation: none;
  opacity: 0.7;
}

/* Static pulse alternative */
.pulse.static {
  background: var(--tesla-red);
  border-radius: 50%;
  opacity: 0.8;
  animation: none;
}

/* Focus indicators for keyboard navigation */
@media (prefers-reduced-motion: reduce) {
  .tesla-focus-indicator {
    box-shadow: 0 0 0 3px rgba(227, 25, 55, 0.5) !important;
  }
}

/* Print styles that also respect reduced motion */
@media print, (prefers-reduced-motion: reduce) {
  .no-print-animation,
  .animated-element {
    animation: none !important;
  }
}
```

Additionally, here's a JavaScript-free alternative using CSS custom properties for progressive enhancement:

```css
/* Progressive enhancement approach */
:root {
  --motion-ok: ;
}

@media (prefers-reduced-motion: no-preference) {
  :root {
    --motion-ok: initial;
  }
}

/* Use in components */
.tesla-component {
  /* Default static state */
  opacity: 1;
  transform: none;
  
  /* Animated state only when motion is OK */
  @media (--motion-ok) {
    transition: opacity var(--duration-normal) var(--ease-tesla),
                transform var(--duration-normal) var(--ease-tesla);
  }
}

/* Alternative: Use data attributes */
[data-motion="reduce"] .animated-element {
  animation: none !important;
  transition: none !important;
}

[data-motion="ok"] .animated-element {
  /* Keep animations */
}
```

This implementation:

1. **Completely disables animations** when `prefers-reduced-motion: reduce` is detected
2. **Provides static alternatives** for key Tesla UI elements
3. **Maintains Tesla's design principles** (minimalism, premium feel, dark mode)
4. **Ensures accessibility** while preserving visual hierarchy
5. **Uses pure CSS** with media queries and utility classes
6. **Includes Tesla-specific components** like battery charging, climate controls, and map animations
7. **Provides focus indicators** for keyboard navigation
8. **Offers progressive enhancement** approach for better compatibility

The solution respects Tesla's design system while ensuring accessibility for users with motion sensitivity or vestibular disorders.


/* ═══ t96 ═══ */
```css

}

@keyframes tesla-scroll-loading {

}

/* Scroll indicator for content that extends beyond viewport */
.tesla-scroll-hint {

  transform: translateX(-50%);
  width: 40px;

  50% { opacity: 1; transform: translateX(-50%) scaleX(1); }
}
```

This CSS provides:

1. **Minimalist Design**: Thin scrollbars with Tesla's signature subtlety
2. **Premium Feel**: Smooth animations, proper transitions, and polished hover states
3. **Dark Theme**: Uses Tesla's color palette with transparent backgrounds
4. **Red Accents**: Scrollbar turns Tesla red when actively being dragged
5. **Mobile Optimization**: Thinner scrollbars on mobile devices
6. **Component-Specific Styling**: Different treatments for cards, modals, and data tables
7. **Accessibility**: High contrast mode support and proper sizing
8. **Tesla Animations**: Uses Tesla's custom easing curves and durations

The implementation follows all Tesla design principles while maintaining pure CSS compatibility across modern browsers.


/* ═══ t97 ═══ */
```css
/* Tesla Text Selection Styling */
::selection {
  background-color: var(--tesla-red);
  color: var(--tesla-white);
  text-shadow: none;
}

::-moz-selection {
  background-color: var(--tesla-red);
  color: var(--tesla-white);
  text-shadow: none;
}

/* For code blocks and preformatted text */
pre::selection,
code::selection {
  background-color: var(--tesla-red-dark);
  color: var(--tesla-white);
}

pre::-moz-selection,
code::-moz-selection {
  background-color: var(--tesla-red-dark);
  color: var(--tesla-white);
}

/* Disabled text selection styling */
.no-select {

  -moz-user-select: none;
  -ms-user-select: none;
}

/* Smooth selection animation */
* {
  transition: background-color var(--duration-fast) var(--ease-tesla);
}
```

**Implementation Notes:**
- Uses Tesla's signature red (`#E31937`) for selection background
- Pure white text ensures maximum contrast and readability
- Darker red variant used for code blocks for better visual hierarchy
- Includes both standard `::selection` and `::-moz-selection` for Firefox compatibility
- Maintains Tesla's minimal aesthetic with clean, uncluttered styling
- Follows Tesla's animation guidelines with fast, smooth transitions
- Text shadow removed to maintain Tesla's clean typography standards
- Optional `.no-select` utility class for elements where selection should be disabled (following Tesla's intentional design philosophy)

}
```

This CSS provides:

1. **Tesla-branded focus rings** using the signature red (#E31937) with appropriate opacity for accessibility
2. **Dual-layer shadows** for better visibility across backgrounds
3. **Element-specific adjustments** for buttons, inputs, cards, and navigation
4. **High contrast mode support** for users who need it
5. **Reduced motion consideration** for accessibility
6. **Clean removal** of default browser outlines
7. **:focus-visible** pseudo-class for keyboard-only focus indication
8. **Print-friendly** styles that hide focus rings

The design maintains Tesla's minimalist aesthetic while ensuring WCAG 2.1 AA compliance for focus indicators. The red color provides sufficient contrast (3:1 minimum) against both dark and light backgrounds when used with the opacity settings.

This print stylesheet follows Tesla's minimalist design principles while optimizing for print output:

1. **Removes all interactive elements** (buttons, inputs, navigation)
2. **Converts dark UI to high-contrast black/white** for readability
3. **Preserves important data** (metrics, statistics, content)
4. **Adds URLs after links** for reference
5. **Optimizes typography** with appropriate print sizes
6. **Removes decorative elements** (shadows, animations, gradients)
7. **Maintains Tesla's clean aesthetic** in printed form
8. **Handles page breaks** to avoid splitting important content
9. **Shows data values** while hiding UI chrome
10. **Includes print metadata** (timestamp, URLs)

The stylesheet ensures Tesla UI content prints cleanly while maintaining the essential information users need on paper.

**Key GPU Acceleration Principles Applied:**

1. **`transform: translateZ(0)`** - Forces element onto GPU layer
2. **`backface-visibility: hidden`** - Optimizes 3D transformations
3. **`perspective: 1000px`** - Enables hardware acceleration
4. **Minimal `will-change` usage** - Only on actively animating elements
5. **Smooth scrolling** - `-webkit-overflow-scrolling: touch` for iOS
6. **Reduced motion support** - Respects user preferences
7. **Mobile optimizations** - Conditional GPU usage for low-power devices

These optimizations ensure Tesla's "Smooth Animations - 60fps, natural easing" principle while maintaining the premium feel and minimalism of the Tesla design system.
