Tokens

Exa's decoded design system: background #FFFFFF, text #000000, accent #000000, link #374151, primary #1F40ED; type scale h1 63.2px / h2 48px / body 18.4px; 4px spacing base; 4px 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.

# Exa — Design System

> light, modern, medium, tailwind

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#EFEFEF` |
| border | `#D8D8D8` |
| text | `#000000` |
| text_muted | `#606060` |
| primary | `#1F40ED` |
| accent | `#000000` |
| link | `#374151` |
| secondary | `#EEF8FF` |
| 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** `#1F40ED` — a brand color — but the call-to-action uses #000000, not this.
- **link** `#374151` — inline text links and link-styled controls.
- **secondary** `#EEF8FF` — 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.

## 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.
