Ghostty's decoded design system: background #0F0F11, text #F0F0F4, accent #3551F3, link #14242D, primary #70B8DB; type scale h1 16px / h2 16px / body 14px; 4px spacing base; 8px base radius. The single interactive/action color is #0F0F11 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

# Ghostty — Design System

> dark, modern, medium, custom

## Colors

| Role | Value |
|------|-------|
| bg | `#0F0F11` |
| surface | `#1C1C1E` |
| border | `#303033` |
| text | `#F0F0F4` |
| text_muted | `#9A9A9D` |
| primary | `#70B8DB` |
| accent | `#3551F3` |
| link | `#14242D` |
| secondary | `#BF8CD9` |
| button_bg | `#0F0F11` |
| button_text | `#F0F0F4` |

**Using these colors**

- **Action color** `#0F0F11` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- **accent** `#3551F3` — accent for emphasis — keep it rare on the page.
- **primary** `#70B8DB` — a brand color — but the call-to-action uses #0F0F11, not this.
- **link** `#14242D` — fails contrast on the background (~1.2:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
- **secondary** `#BF8CD9` — 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.

Export: Tailwind v4 (@theme)
