Decoded design system

Dust's decoded design system: background #FFFFFF, text #000000, accent #1C91FF, link #E9F7FF, primary #1C91FF; type scale h1 69px / h2 48px / body 16px; 4px spacing base; 0px base radius. The single interactive/action color is #1C91FF — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #1C91FF — the single interactive color; only on things you click or must notice, never large fills.
• primary, accent, button_bg are all #1C91FF — one role, not several (the action color).
• accent #1C91FF — 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.
• link #E9F7FF — 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).
• secondary #596170 — 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.

# Dust — Design System

> light, modern, high, tailwind — deep decode (measured live)

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#EFEFEF` |
| border | `#D8D8D8` |
| text | `#000000` |
| text_muted | `#606060` |
| primary | `#1C91FF` |
| accent | `#1C91FF` |
| link | `#E9F7FF` |
| secondary | `#596170` |
| button_bg | `#1C91FF` |
| button_text | `#E9F7FF` |

**Using these colors**

- **Action color** `#1C91FF` — 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`, `button_bg` are all `#1C91FF` — one role, not several (your action color).
- **accent** `#1C91FF` — 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.
- **link** `#E9F7FF` — 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).
- **secondary** `#596170` — 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` 68.7% · `#262D3F` 18.8% · `#1D72C6` 7.1% · `#82B7E3` 3.6%

## Typography

- Heading: **Geist**
- Body: **Geist**
- Mono: **Geist Mono** _(measured)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 69px / 550 · lh 62px · tracking -2.76px |
| h2 | 48px / 450 · lh 52px · tracking -2.88px |
| h3 | 24px / 550 · lh 30px · tracking -0.6px |
| body | 16px / 400 · lh 24px · tracking -0.32px |
| small | 15px / 400 · lh 21px · tracking -0.5px |
| eyebrow | 10px / 450 · tracking 0.44px |

- Weight ladder: 400 · 450 · 500 · 550 — use these exact measured weights, not the 400/600 defaults.

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

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 2px, 4px, 6px, 8px, 12px, 16px, 20px, 24px, 28px, 40px — snap all gaps/padding to these
- section rhythm: 96px top/bottom padding per section (measured)

## Radius
- base: 0px
- button: 16px
- card: 16px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `oklch(0.6539 0.1893 252.74)` / `oklch(0.9681 0.0183 232.5)` | 1px solid rgba(0, 0, 0, 0) | 16px | 8px 16px 8px 16px | 400 16px | none |
| secondary | `oklch(1 0 0)` / `oklch(0.256 0.006 34.298)` | 1px solid oklch(0.97 0.001 106.424) | 12px | 0px 12px 0px 12px | 400 16px | none |

**States (measured, not guessed)**

- primary hover: background `oklch(0.7215 0.1521 248.14)`
- secondary hover: border `1px solid oklch(0.949 0.003 106.45)` · background `oklch(0.97 0.001 106.424)`
- transition: `color 0.15s cubic-bezier(0.4, 0, 0.2, 1)`

## Motion
- durations: 500ms (dominant) · 180ms · 300ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `ease`
- animated properties: opacity, transform, fill, color

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

## 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.
