Decoded design system

Cohere's decoded design system: background #FFFFFF, text #000000, accent #D7CFC1, link #FAFAFA, primary #75758A; type scale h1 96px / h2 48px / body 16px; 8px spacing base; 7px base radius. The single interactive/action color is #17171C — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #17171C — the single interactive color; only on things you click or must notice, never large fills.
• accent #D7CFC1 — accent for emphasis — keep it rare on the page.
• primary #75758A — a neutral UI color (chips, tags, icon fills, chrome), not the action color (action = #17171C).
• link #FAFAFA — fails contrast on the background (~1.0:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
• secondary #9B60AA — 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.

# Cohere — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#EFEFEF` |
| border | `#D8D8D8` |
| text | `#000000` |
| text_muted | `#606060` |
| primary | `#75758A` |
| accent | `#D7CFC1` |
| link | `#FAFAFA` |
| secondary | `#9B60AA` |
| button_bg | `#17171C` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#17171C` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- **accent** `#D7CFC1` — accent for emphasis — keep it rare on the page.
- **primary** `#75758A` — a neutral UI color (chips, tags, icon fills, chrome), not the action color (action = #17171C).
- **link** `#FAFAFA` — fails contrast on the background (~1.0:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
- **secondary** `#9B60AA` — 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): `#FFFFFF` 58.5% · `#17171B` 24.5% · `#4D4447` 7.1% · `#95848E` 6.7%

## Typography

- Heading: **Arial**
- Body: **Arial**
- Mono: **CohereMono** _(measured)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 96px / 400 · lh 96px · tracking -1.92px |
| h2 | 48px / 400 · lh 58px · tracking -0.48px |
| h3 | 32px / 400 · lh 38px · tracking -0.32px |
| body | 16px / 400 · lh 24px |
| small | 14px / 400 · lh 20px |

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

> **Fonts —** Arial — system font, no web load needed.

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 4px, 6px, 8px, 12px, 16px, 20px, 24px, 32px, 36px, 40px — snap all gaps/padding to these
- section rhythm: 80px top/bottom padding per section (measured)

## Radius
- base: 7px
- button: 9999px
- card: 4px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#17171C` / `#FFFFFF` | none | 9999px | 12px 16px 12px 16px | 400 16px | none |
| secondary | `rgba(0, 0, 0, 0)` / `#212121` | none | 9999px | 0px 0px 6px 0px | 400 16px | none |

**States (measured, not guessed)**

- primary hover: background `#000000`
- transition: `background-color 0.3s ease`

## Shadows (elevation)
- card: `rgba(172, 171, 171, 0.3) 0px -1px 10px 0px`

## Motion
- durations: 500ms (dominant) · 300ms · 150ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `ease-in-out`
- animated properties: opacity, transform, color, background-color

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 |
|-------|-------|
| `--volcanic` | `#212121` |
| `--marble` | `#fafafa` |
| `--green` | `#39594d` |
| `--coral` | `#ff7759` |
| `--coral-light` | `rgb(255 173 155)` |

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

## Layout (measured)
- container max 1128px · common grid: 3-col
- nav: 76px fixed · bg #FFFFFF

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 0 | 466 | — | — | 160/80 | — |

| 1066 | 307 | — | — | 40/80 | — |
| 1374 | 611 | 3 | 20 | 80/144 | — |
| 1984 | 900 | 3 | — | 160/0 | — |

## Motion choreography (measured)
Load order: `div.flex`×2 @0ms → `div.mb-10` @1ms → `` @1ms → `div.flex` @1ms → `div.absolute`×2 @214ms → `` @275ms
- `?` — opacity 0→1 · transform translateY(25%)→translateY(0px) — 500ms ease-in-out
- `div.flex` — opacity 0→1 — 500ms cubic-bezier(0.4, 0, 0.2, 1)
- `div.flex` ×2 — opacity 0→1 · transform translateY(25%)→translateY(0px) — 500ms ease-in-out
- `div.mb-10` — opacity 0→1 · transform translateY(25%)→translateY(0px) — 500ms ease-in-out
- `?` — opacity 0→1 · transform translateY(25%)→translateY(0px) — 500ms ease-in-out
- `div.flex` — opacity 0→1 — 1000ms ease
- stagger: `div` ×14 — 100ms apart
- scroll reveal: 40 elements rest at opacity 0, animate in over 0.5s cubic-bezier(0.4, 0, 0.2, 1) (4 revealed during the drive).
- overlay dialog (auto-opened): panel #FFFFFF · r 8px

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

## Components (measured)
- link: #171717 · underline
- disabled: bg rgba(0, 0, 0, 0) · text #212121

## Responsive (measured)
- breakpoints: 336px · 410px · 425px · 440px · 460px · 480px
- mobile (390px): hero 60px · body 16px · 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.
