Decoded design system

Colophon's decoded design system: background #F8F8F8, text #000000, accent #FFEE3B, link #FFFFFF, primary #FFEE3B; type scale h1 36px / h2 24px / body 24px; 5px spacing base; 0px base radius. The single interactive/action color is #346E4A — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#F8F8F8`
surface	`#E9E9E9`
border	`#D2D2D2`
text	`#000000`
text_muted	`#5E5E5E`
primary	`#FFEE3B`
accent	`#FFEE3B`
link	`#FFFFFF`
button_bg	`#346E4A`
button_text	`#FFFFFF`

Using these colors

Action color #346E4A — the single interactive color; only on things you click or must notice, never large fills.
primary, accent are all #FFEE3B — one role, not several (the action color).
accent #FFEE3B — accent for emphasis — keep it rare on the page.
link #FFFFFF — fails contrast on the background (~1.1:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).

# Colophon — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#F8F8F8` |
| surface | `#E9E9E9` |
| border | `#D2D2D2` |
| text | `#000000` |
| text_muted | `#5E5E5E` |
| primary | `#FFEE3B` |
| accent | `#FFEE3B` |
| link | `#FFFFFF` |
| button_bg | `#346E4A` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#346E4A` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `primary`, `accent` are all `#FFEE3B` — one role, not several.
- **accent** `#FFEE3B` — accent for emphasis — keep it rare on the page.
- **link** `#FFFFFF` — fails contrast on the background (~1.1:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
- **Page coverage** (full-page screenshot pixels): `#FEEE35` 56.6% · `#F9F9FA` 29% · `#81844F` 14.3%

## Typography

- Heading: **CF Basis** _(free fallback: Newsreader)_
- Body: **CF Basis** _(free fallback: Newsreader)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 36px / 400 |
| body | 24px / 400 |
| small | 16px / 400 |

- Weight ladder: 400 · 500 · 600 · 700 — use these exact measured weights, not the 400/600 defaults.

> **Fonts —** CF Basis may be proprietary — safe free fallback: Newsreader (Google Fonts).

## Spacing
- base unit: 5px (inferred from the measured scale)
- measured scale: 6px, 10px, 12px, 15px, 20px, 24px, 30px, 32px, 48px, 60px — snap all gaps/padding to these
- section rhythm: 48px top/bottom padding per section (measured)

## Radius
- base: 0px
- button: 2px
- card: 50px
- sharp: 2px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#346E4A` / `#FFFFFF` | 1px solid rgb(255, 255, 255) | 2px | 12px 10px 12px 10px | 600 11.382px / 0.5691px | none |

**States (measured, not guessed)**

- primary hover: border `1px solid rgb(136, 136, 136)` · color `#333333`
- primary focus: border `1px solid rgb(136, 136, 136)` · color `#333333` · outline `1px solid rgb(0, 0, 0)`

## Shadows (elevation)
- card: `rgba(0, 0, 0, 0.2) 0px 0px 18px 0px`

## Motion
- durations: 300ms (dominant)
- easings: `ease` (dominant)
- animated properties: background

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

## Layout (measured)
- container max 800px
- nav: 704px relative · bg #FFEE3B

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 1114 | 237 | — | — | 0/48 | — |
| 1399 | 462 | — | — | 0/0 | — |
| 1909 | 196 | — | — | 0/0 | — |

## Motion choreography (measured)
- overlay dialog (auto-opened): panel rgba(0, 0, 0, 0) · r 0px

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

## Components (measured)
- link: #000000 · underline

## Responsive (measured)
- breakpoints: 425px · 550px · 600px · 640px · 768px · 896px
- mobile (390px): hero 20px · body 16px · nav: inline

## 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.
