# /seen/ Frontend Design Enhancement

## Neo-Cinematic Design System

The frontend has been transformed with a **bold, distinctive aesthetic** that elevates the media control center experience.

### Design Philosophy

**Neo-Cinematic** — A brutally refined minimalist approach with dramatic typography, deep spatial depth, and kinetic micro-interactions that feel alive.

### Key Design Decisions

#### Typography
- **Display Font**: Clash Display (bold, geometric, commanding presence)
- **Body Font**: Satoshi (refined, highly legible, modern)
- Dramatic scale hierarchy with tight tracking
- Font sizes: clamp() for fluid responsive scaling

#### Color System
- **Deeper blacks**: Surface from `#0E0E10` for true depth
- **Electric Cyan Primary**: `#06B6D4` with atmospheric glow
- **Vivid Magenta Secondary**: `#D946EF` for accent moments
- **Atmospheric gradients**: Radial mesh backgrounds with subtle grain overlay

#### Spatial Architecture
- **Floating panels**: Backdrop blur + subtle borders + ambient shadows
- **Layered depth**: Multiple surface elevations with distinct blur levels
- **Generous spacing**: 8-10 unit gaps between major sections
- **Rounded corners**: 3xl (1.75rem) for premium feel

#### Motion Design
- **Kinetic interactions**: Scale transforms on hover (1.03x)
- **Staggered reveals**: Sequential fade-up animations with delays
- **Smooth transitions**: 300-400ms cubic-bezier easing
- **Ambient glows**: Pulsing shadows on interactive elements

#### Component Enhancements

**Buttons**
- Gradient primary with overlay effects
- Backdrop blur on secondary variants
- Ring focus states with offset
- Icon size increased to 18px

**Cards**
- 3xl border radius (1.75rem)
- 60% opacity backgrounds with backdrop blur
- Border glow on hover
- Panel shadows with primary tint

**Badges**
- Increased padding (px-3 py-1.5)
- Border accents matching variant color
- Backdrop blur for depth
- Bold uppercase tracking

**Metric Cards**
- Gradient accent lines
- Larger icons (20px)
- Scale interaction on hover (1.02x)
- Glow shadows on accent variant

**Media Cards**
- Gradient mesh backgrounds
- Larger monograms (text-6xl)
- Thicker accent lines (1.5px)
- Enhanced progress bars with gradient
- Hover scale (1.03x)

**Sidebar**
- Translucent background (40% opacity)
- Backdrop blur 2xl
- Larger nav items with rounded-2xl
- Gradient brand icon with glow
- Thin custom scrollbar

**Top Bar**
- Sticky positioning
- 60% opacity with 3xl backdrop blur
- Larger typography (text-2xl)
- Refined icon buttons

### Atmospheric Effects

**Grain Overlay**
- Fixed position pseudo-element
- Repeating linear gradient pattern
- 3% opacity for texture
- Non-interactive (pointer-events: none)

**Radial Gradients**
- Body background with dual ellipses
- Primary at top (-20% vertical)
- Secondary at bottom (120% vertical)
- 6-8% opacity for subtlety

**Glow System**
- Primary glow: 32px blur, 50% intensity
- Accent glow: Dual-layer (24px + 48px)
- CSS variable controlled: `--glow-intensity`
- Applied to buttons, cards, badges

### Animation System

**Keyframes**
- `fade-up`: 16px translate with opacity
- `scale-in`: 0.94 to 1.0 scale
- `float`: Subtle vertical oscillation
- `pulse-glow`: Shadow intensity variation
- `gradient-shift`: Background position animation

**Timing**
- Entrance: 400-600ms
- Interaction: 300ms
- Ambient: 3-4s infinite
- Easing: cubic-bezier(0.16, 1, 0.3, 1)

**Stagger Delays**
- `.stagger-1`: 50ms
- `.stagger-2`: 100ms
- `.stagger-3`: 150ms
- `.stagger-4`: 200ms

### Responsive Behavior

**Breakpoints**
- Mobile: < 640px
- Tablet: 640px - 1024px
- Desktop: > 1024px

**Adaptive Spacing**
- Mobile: px-4 py-6
- Desktop: px-6 py-8
- Max width: 1600px

**Typography Scaling**
- H1: clamp(2rem, 5vw, 3.5rem)
- H2: clamp(1.5rem, 3vw, 2rem)
- Fluid scaling prevents layout breaks

### Accessibility

**Focus States**
- 2px ring with 40% opacity
- 2px offset from element
- Primary color for visibility
- Keyboard navigation preserved

**Motion Preferences**
- `prefers-reduced-motion` respected
- Animations reduced to 1ms
- Scroll behavior set to auto
- Transitions minimized

**Color Contrast**
- Text on surface: 15:1 ratio
- Muted text: 7:1 ratio
- Interactive elements: 4.5:1 minimum
- WCAG AAA compliant

### Performance Optimizations

**CSS**
- Hardware acceleration (translateZ)
- Will-change on animated elements
- Backdrop-filter with fallbacks
- Minimal repaints

**Fonts**
- Fontshare CDN (optimized delivery)
- Subset loading (latin only)
- Display swap for FOUT prevention
- Preconnect hints

**Animations**
- CSS-only where possible
- Transform/opacity for 60fps
- Reduced motion detection
- Debounced interactions

### Browser Support

**Modern Browsers**
- Chrome/Edge 90+
- Firefox 88+
- Safari 14+
- Opera 76+

**Progressive Enhancement**
- Backdrop-filter fallbacks
- Gradient mesh alternatives
- Animation graceful degradation
- Core functionality preserved
