# Night Lime

## Overview

Acid lime on charcoal, a nighttime playlist. The atmosphere is daily-app balanced, offset and asymmetric, with fluid CSS motion. Tone: nocturnal, bold, media. Density 6/10, variance 5/10, motion 6/10. Material: Charcoal ground, acid-lime accent, cover tiles — a nighttime playlist.

How to use: Place this file at the repository root. Tell Cursor / Claude Code / Codex: read DESIGN.md and obey its tokens and Do/Don'ts.

## Colors

Semantic roles for the light theme. Keep a single accent; do not introduce a second brand hue.

- **primary** (`#1DB954`)
- **secondary** (`#535353`)
- **tertiary** (`#191414`)
- **background** (`#F6F6F6`)
- **surface** (`#FFFFFF`)
- **outline** (`#E5E5E5`)
- **muted** (`#535353`)
- **success** (`#1DB954`)
- **warning** (`#F59E0B`)
- **error** (`#E91429`)
- **onPrimary** (`#F4F4F5`)
- **onSecondary** (`#F4F4F5`)
- **onTertiary** (`#F4F4F5`)
- **onBackground** (`#18181B`)
- **onSurface** (`#18181B`)

## Typography

Hierarchy comes from weight and size, not from shouting. Body line length stays near 65 characters.

- **h1**: Outfit 600 / 40px / 1.12 / -0.03em
- **h2**: Outfit 600 / 28px / 1.2 / -0.02em
- **h3**: Outfit 600 / 20px / 1.3 / -0.01em
- **body**: "DM Sans" 400 / 16px / 1.55 / 0em
- **label**: "DM Sans" 500 / 13px / 1.3 / 0.02em
- **caption**: "DM Sans" 400 / 12px / 1.4 / 0em
- **mono**: "JetBrains Mono" 500 / 13px / 1.45 / 0em

## Layout

Spacing scale: xs=4px, sm=8px, md=16px, lg=24px, xl=32px, 2xl=48px, 3xl=64px.

iOS: 44pt targets, respect Safe Area and Dynamic Type, SF Symbols, Large Titles and grouped lists.

Web: mobile-first, single column below 768px, body ≥ 16px, clamp() headlines, max-width 1120–1400px, min-h-[100dvh] for full-height sections.

Every element occupies its own spatial zone. No overlapping hero text. Collapse multi-column layouts below 768px.

## Elevation & Depth

- sm: `0 1px 2px rgba(24,24,27,0.06)`
- md: `0 8px 24px rgba(24,24,27,0.08)`
- lg: `0 18px 48px rgba(24,24,27,0.12)`
- surface: `flat`
- recipe: Charcoal ground, acid-lime accent, cover tiles — a nighttime playlist.

Tint shadows toward the background hue. High-density layouts may replace cards with hairline dividers.


## Shapes

Radius scale: sm=4px, md=8px, lg=12px, xl=20px, full=999px.

## Components

- **Navbar** (`web.navbar` / default / md): Desktop nav with logo, icon links, and one primary CTA.
- **Hero** (`web.hero` / left / lg): Hero uses left layout, one CTA, no "Scroll to explore".
- **Media** (`media` / wide / md): Geometric cover, radius from tokens. No remote images.
- **List Item** (`list-item` / chevron / md): Min 44pt rows, title + subtitle, optional chevron.
- **List Item** (`list-item` / chevron / md): Min 44pt rows, title + subtitle, optional chevron.
- **List Item** (`list-item` / chevron / md): Min 44pt rows, title + subtitle, optional chevron.
- **Player** (`player` / mini / md): Mini player: art, title, scrubber. Ship system Now Playing.
- **Footer** (`web.footer` / default / md): Quiet footer with clear link groups.

## Do's and Don'ts

### Do
- Use semantic color tokens, never raw hex in components.
- Keep a single accent; hierarchy comes from type weight and space.
- Define default, hover, focus-visible, pressed, disabled, and loading states.
- Meet WCAG 2.2 AA contrast for body text and interactive labels.
- Touch targets are at least 44×44pt on iOS and 44px on web.

### Don't
- Do not use Inter as the display face for premium work.
- Do not use pure black #000000 for large surfaces.
- Do not add neon outer glows or custom mouse cursors.
- Do not ship three equal feature cards as the default layout.
- Do not hide focus rings or drop below AA contrast.
