Decoded design system

Mistral AI's decoded design system: background #FBFBF8, text #000000, accent #F4F4F5, link #000000, primary #000000; type scale h1 96px / h2 56px / body 13px; 8px spacing base; 0px base radius. The single interactive/action color is #F4F4F5 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #F4F4F5 — the single interactive color; only on things you click or must notice, never large fills.
• primary, link are all #000000 — one role, not several (the action color).
• accent, button_bg are all #F4F4F5 — one role, not several (the action color).
• accent #F4F4F5 — 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.

# Mistral AI — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#FBFBF8` |
| surface | `#EBEBE9` |
| border | `#D5D5D2` |
| text | `#000000` |
| text_muted | `#5F5F5E` |
| primary | `#000000` |
| accent | `#F4F4F5` |
| link | `#000000` |
| button_bg | `#F4F4F5` |
| button_text | `#18181B` |

**Using these colors**

- **Action color** `#F4F4F5` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `primary`, `link` are all `#000000` — one role, not several.
- `accent`, `button_bg` are all `#F4F4F5` — one role, not several (your action color).
- **accent** `#F4F4F5` — 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.
- **Page coverage** (full-page screenshot pixels): `#FBFBF8` 73.9% · `#EB5A19` 12% · `#AA1511` 10.3% · `#CECCC9` 3.9%

## Typography

- Heading: **Inter**
- Body: **Inter**
- Mono: **Space Mono**

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 96px / 500 · lh 96px · tracking -1.92px |
| h2 | 56px / 500 · lh 60px · tracking -0.56px |
| h3 | 44px / 500 · lh 52px · tracking -0.44px |
| body | 13px / 400 · lh 20px |
| small | 11px / 400 · lh 16px |

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

> **Fonts —** Inter — free, on Google.

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 4px, 8px, 12px, 16px, 24px, 32px, 40px, 80px, 160px — snap all gaps/padding to these
- section rhythm: 40px top/bottom padding per section (measured)

## Radius
- base: 0px
- button: 0px
- card: 6px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `oklch(0.141 0.005 285.823)` / `oklch(0.985 0 0)` | none | 0px | 0px 16px 0px 16px | 400 14px | none |

**States (measured, not guessed)**

- primary hover: background `oklch(0.21 0.006 285.885)`
- primary focus: outline `1px auto rgb(16, 16, 16)`
- transition: `color 0.15s cubic-bezier(0.4, 0, 0.2, 1)`

## Motion
- durations: 300ms (dominant) · 150ms · 500ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `ease`
- animated properties: transform, translate, scale, rotate

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

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

## Layout (measured)

## Motion choreography (measured)
Load order: `span.relative`×3 @0ms → `img.absolute`×6 @294ms → `img.block`×11 @294ms → `` @405ms → `div.max-w-432` @615ms → `a.flex`×6 @615ms
- `?` — opacity 0→1 — 600ms ease-in-out (delay 300ms)
- `span.relative` ×3 — opacity 0.2→1 — 2000ms · loops
- stagger: `span` ×3 — 200ms apart
- stagger: `img` ×3 — 50ms apart
- scroll reveal: 15 elements rest at opacity 0, translateY(-100px), animate in over 0.5s cubic-bezier(0.4, 0, 0.2, 1) (12 revealed during the drive).

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

## Components (measured)
- card ×12: pad 0px 0px 0px 0px · r 0px · border 1px solid rgb(228, 227, 222) · bg rgba(0, 0, 0, 0)
  - hover: background `#F5F4EF` · font-weight `400` · letter-spacing `normal`

## 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.
