# Astro — Design System

> dark, modern, medium, tailwind

## Colors

| Role | Value |
|------|-------|
| bg | `#060913` |
| surface | `#131620` |
| border | `#282B33` |
| text | `#ECECEE` |
| text_muted | `#94959A` |
| primary | `#1F232E` |
| accent | `#61DAFB` |
| link | `#61DAFB` |
| secondary | `#183341` |
| button_bg | `#FFFFFF` |
| button_text | `#F2F6FA` |

**Using these colors**

- **Action color** `#FFFFFF` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `accent`, `link` are all `#61DAFB` — one role, not several.
- **accent** `#61DAFB` — accent for emphasis — keep it rare on the page.
- **primary** `#1F232E` — a brand color — but the call-to-action uses #FFFFFF, not this.
- **secondary** `#183341` — 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.

## Typography

- Heading: **Obviously** _(free fallback: Newsreader)_
- Body: **Inter**
- h1: 48px
- h2: 36px
- body: 18px

> **Fonts —** Obviously may be proprietary — safe free fallback: Newsreader (Google Fonts). Inter — free, on Google.

## Spacing
- base unit: 4px
- scale: 2px, 4px, 6px, 8px, 12px, 16px, 24px, 32px

## Radius
- base: 8px
- button: 9999px

## Primary button
- bg `#FFFFFF` · text `#F2F6FA` · radius 9999px

## 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.
