Decoded design system

Ghost's decoded design system: background #FFFFFF, text #000000, accent #D1FF19, link #94A3B8, primary #94A3B8; type scale h1 96px / h2 48px / body 24px; 8px spacing base; 5px base radius. The single interactive/action color is #FEC137 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #FEC137 — the single interactive color; only on things you click or must notice, never large fills.
• primary, link are all #94A3B8 — one role, not several (the action color).
• accent #D1FF19 — accent for emphasis — keep it rare on the page.

**Using these colors**

- **Action color** `#FEC137` — 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 `#94A3B8` — one role, not several.
- **accent** `#D1FF19` — accent for emphasis — keep it rare on the page.
- **Page coverage** (full-page screenshot pixels): `#FFFFFF` 58.3% · `#101213` 38.6% · `#4E4F4B` 3.1%

## Typography

- Heading: **InterDisplay** _(free fallback: Newsreader)_

- Weight ladder: 400 · 500 · 600 · 700 — use these exact measured weights, not the 400/600 defaults.

> **Fonts —** InterDisplay may be proprietary — safe free fallback: Newsreader (Google Fonts). InterVariable may be proprietary — safe free fallback: Newsreader (Google Fonts).

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 3px, 8px, 12px, 16px, 20px, 24px, 27px, 28px, 36px, 54px — snap all gaps/padding to these
- section rhythm: 72px top/bottom padding per section (measured)

## Radius
- base: 5px
- button: 9999px
- card: 24px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#FEC137` / `#000000` | none | 9999px | 8px 3px 8px 3px | 400 15px | none |
| secondary | `#15171A` / `#FFFFFF` | 1px solid rgba(0, 0, 0, 0) | 6px | 8px 16px 8px 16px | 400 14px | rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.1) 0px 0px 1px 0px, rgba(0, 0, 0, 0.03) 0px 2px 6px 0px |

**States (measured, not guessed)**

- primary focus: outline `1px auto rgb(16, 16, 16)`
- transition: `all 0.3s cubic-bezier(0.4, 0, 0.2, 1)`

## Shadows (elevation)
- subtle: `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.1) 0px 0px 1px 0px, rgba(0, 0, 0, 0.03) 0px 2px 6px 0px`

## Motion
- durations: 300ms (dominant)
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant)

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.
