Decoded design system

Coda's decoded design system: background #FFFFFF, text #212121, accent #000000, link #FFE6C9, primary #FFF6EC; type scale h1 72px / h2 38px / body 14px; 4px spacing base; 8px base radius. The single interactive/action color is #000000 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #000000 — the single interactive color; only on things you click or must notice, never large fills.
• accent, button_bg are all #000000 — one role, not several (the action color).
• accent #000000 — THE accent / action color — interactive & must-notice only (buttons, links, focus, one key highlight); never large fills or backgrounds. Scarcity is what makes it read as designed.
• primary #FFF6EC — a neutral UI color (chips, tags, icon fills, chrome), not the action color (action = #000000).
• link #FFE6C9 — fails contrast on the background (~1.2:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
• secondary #00ABEC — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.

# Coda — Design System

> light, modern, medium, custom — deep decode (measured live)

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#F1F1F1` |
| border | `#DDDDDD` |
| text | `#212121` |
| text_muted | `#757575` |
| primary | `#FFF6EC` |
| accent | `#000000` |
| link | `#FFE6C9` |
| secondary | `#00ABEC` |
| button_bg | `#000000` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#000000` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `accent`, `button_bg` are all `#000000` — one role, not several (your action color).
- **accent** `#000000` — THE accent / action color — interactive & must-notice only (buttons, links, focus, one key highlight); never large fills or backgrounds. Scarcity is what makes it read as designed.
- **primary** `#FFF6EC` — a neutral UI color (chips, tags, icon fills, chrome), not the action color (action = #000000).
- **link** `#FFE6C9` — fails contrast on the background (~1.2:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
- **secondary** `#00ABEC` — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.
- **Page coverage** (full-page screenshot pixels): `#FDF5FF` 50.5% · `#FFE6C9` 37.4% · `#A37A66` 10% · `#F3EBE6` 2.1%

## Typography

- Heading: **Calibre** _(free fallback: Newsreader)_
- Body: **Inter**

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 72px / 700 · lh 72px · tracking -3.24px |
| h2 | 38px / 700 · lh 42px · tracking -0.95px |
| h3 | 22px / 400 · lh 34px · tracking -0.66px |
| body | 14px / 600 · lh 20px · tracking -0.14px |
| small | 13px / 600 · lh 16px · tracking 0.13px |

- Weight ladder: 400 · 600 · 700 — use these exact measured weights, not the 400/600 defaults.

> **Fonts —** Calibre may be proprietary — safe free fallback: Newsreader (Google Fonts). Inter — free, on Google.

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 2px, 4px, 8px, 10px, 12px, 16px, 20px, 24px, 28px, 29px — snap all gaps/padding to these

## Radius
- base: 8px
- button: 8px
- card: 8px
- sharp: 2px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#000000` / `#FFFFFF` | none | 8px | 8px 12px 8px 12px | 600 16px / -0.48px | rgb(33, 33, 33) 0px 0px 0px 1.5px inset |
| secondary | `#FFFFFF` / `#212121` | none | 8px | 8px 12px 8px 12px | 600 16px / -0.48px | rgb(224, 224, 224) 0px 0px 0px 1.5px inset |

**States (measured, not guessed)**

- primary hover: box-shadow `rgba(0, 20, 20, 0.2) 0px 8px 24px 0px` · background `#212121` · transform `matrix(1.02, 0, 0, 1.02, 0, 0)`
- secondary hover: background `#F5F5F5`
- transition: `all 0.05s ease`

## Shadows (elevation)
- card: `rgba(0, 0, 0, 0.06) 0px 12px 24px -5px, rgba(0, 0, 0, 0.06) 0px 5px 10px -6px`
- button: `rgb(33, 33, 33) 0px 0px 0px 1.5px inset`

## Motion
- durations: 150ms (dominant) · 50ms · 250ms
- easings: `ease` (dominant)
- animated properties: transform, background-color, color, fill

Micro-interactions use the dominant duration + easing; nothing on the page animates slower than the longest duration above — don't invent springier motion.

## Their own tokens (verbatim from :root)

| Token | Value |
|-------|-------|
| `--header-background-rbga` | `rgba(255,255,255,100%)` |
| `--header-no-background-rbga` | `rgba(255,255,255,0%)` |
| `--sanity-header-padding-size` | `32px 32px` |

Prefer these names when extending their system — it's the brand's actual vocabulary.

## Layout (measured)
- container max 1200px
- nav: 141px sticky · border-bottom 1px solid rgba(0, 0, 0, 0.1) · bg #FFFFFF

## Motion choreography (measured)
Load order: `div.otFlat` @0ms
- `a.FX28sb0q` ×4 — opacity 0→0 — 100ms
- `div.ALRU8pEW` ×5 — opacity 0→0 — 100ms
- `div.Btm7P6tl` — opacity 1→1 — 300ms
- `a.SCHmmVgT` ×2 — opacity 0→0 — 100ms (delay 10ms)
- `a.nOwKUoMF` ×8 — opacity 0→0 — 100ms (delay 10ms)
- `a` ×4 — opacity 0→0 — 100ms (delay 20ms)

Rebuild the timeline, not just the durations — order, delays and staggers above are the choreography.

## Responsive (measured)
- breakpoints: 500px · 550px · 600px · 699px · 896px · 920px
- mobile (390px): body 14px · nav: hamburger

## How to apply
Paste the Tailwind `@theme` (or CSS variables) as your base, then build each
section to its spec — verify every color, radius, and font against these tokens.
Hover/focus states, shadows and motion timings above are measured from the live page — match them exactly, don't re-guess them.
