# Paper
## Overview
Ink on warm paper — a notebook left open. The atmosphere is daily-app balanced, offset and asymmetric, with fluid CSS motion. Tone: warm, quiet, tactile. Density 4/10, variance 5/10, motion 4/10. Material: Warm paper fill, 0.5–1px ink rules, shadows tinted toward the paper. No pure-white cards on a colored ground.
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** (`#8C4A32`)
- **secondary** (`#7A6A58`)
- **tertiary** (`#C4A574`)
- **background** (`#F6F1E8`)
- **surface** (`#FFFBF4`)
- **outline** (`#E4D8C4`)
- **muted** (`#8A7B68`)
- **success** (`#3F7A55`)
- **warning** (`#B5812F`)
- **error** (`#B24A3A`)
- **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**: Fraunces 600 / 40px / 1.12 / -0.03em
- **h2**: Fraunces 600 / 28px / 1.2 / -0.02em
- **h3**: Fraunces 600 / 20px / 1.3 / -0.01em
- **body**: Newsreader 400 / 16px / 1.55 / 0em
- **label**: Newsreader 500 / 13px / 1.3 / 0.02em
- **caption**: Newsreader 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 0 rgba(92,64,40,0.08)`
- md: `0 10px 30px rgba(92,64,40,0.08)`
- lg: `0 24px 50px rgba(92,64,40,0.12)`
- surface: `paper`
- recipe: Warm paper fill, 0.5–1px ink rules, shadows tinted toward the paper. No pure-white cards on a colored ground.
Tint shadows toward the background hue. High-density layouts may replace cards with hairline dividers.
## Shapes
Radius scale: sm=2px, md=6px, lg=10px, xl=16px, 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".
- **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.
- **List Item** (`list-item` / chevron / md): Min 44pt rows, title + subtitle, optional chevron.
- **Card** (`card` / outline / md): Cards only when elevation communicates hierarchy.
- **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.
