Tokens

Hume's decoded design system: background #FFF9F3, text #222222, accent #E8739E, link #E8739E, primary #E8739E; type scale h1 48px / body 16px; 8px spacing base; 0px base radius. The single interactive/action color is #FFFAF4 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#FFF9F3`
surface	`#F1ECE6`
border	`#DDD8D3`
text	`#222222`
text_muted	`#757371`
primary	`#E8739E`
accent	`#E8739E`
link	`#E8739E`
button_bg	`#FFFAF4`
button_text	`#FFFFFF`

Using these colors

Action color #FFFAF4 — the single interactive color; only on things you click or must notice, never large fills.
primary, accent, link are all #E8739E — one role, not several (the action color).
accent #E8739E — accent for emphasis — keep it rare on the page.

# Hume — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#FFF9F3` |
| surface | `#F1ECE6` |
| border | `#DDD8D3` |
| text | `#222222` |
| text_muted | `#757371` |
| primary | `#E8739E` |
| accent | `#E8739E` |
| link | `#E8739E` |
| button_bg | `#FFFAF4` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#FFFAF4` — 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`, `link` are all `#E8739E` — one role, not several.
- **accent** `#E8739E` — accent for emphasis — keep it rare on the page.
- **Page coverage** (full-page screenshot pixels): `#FFF9F3` 89.9% · `#F1D5D4` 8.2% · `#B499A1` 2%

## Typography

- Heading: **Fellix** _(free fallback: Newsreader)_
- Body: **Fellix** _(free fallback: Newsreader)_
- Mono: **PP Fraktion Mono** _(measured)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 48px / 520 · lh 48px · tracking -1.2px |
| h2 | 36px / 520 · lh 40px · tracking -0.9px |
| h3 | 30px / 520 · lh 36px · tracking -0.75px |
| body | 14px / 400 · lh 20px |
| small | 12px / 400 · lh 16px · tracking 0.3px |
| eyebrow | 12px / 400 · tracking 0.3px |

- Weight ladder: 400 · 520 — use these exact measured weights, not the 400/600 defaults.

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

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 4px, 8px, 12px, 16px, 20px, 24px, 32px, 48px, 64px, 96px — snap all gaps/padding to these
- section rhythm: 112px top/bottom padding per section (measured)

## Radius
- base: 0px
- button: 9999px
- card: 8px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#222222` / `#FFF9F3` | none | 3.35544e+07px | 8px 16px 8px 16px | 400 14px | none |
| secondary | `#222222` / `#FFF9F3` | none | 9999px | — | — | none |

**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)`

## Motion
- durations: 150ms (dominant) · 200ms · 300ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `cubic-bezier(0, 0, 0.2, 1)`
- animated properties: background-color, color, border-color, outline-color

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

## Their own tokens (verbatim from :root)

| Token | Value |

## Motion choreography (measured)
- scroll reveal: 14 elements rest at opacity 0, translateY(24px) (14 revealed during the drive).

Rebuild the timeline, not just the durations — order, delays and staggers above are the choreography.

## Responsive (measured)

- mobile (390px): hero 30px · body 16px · nav: hamburger

## 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.
