Decoded design system

Function Health's decoded design system: background #FEF9EF, text #2A2B2F, accent #B05A36, link #FEF9EF, primary #FEF9EF; type scale h1 80px / h2 64px / body 16px; 4px spacing base; 12px base radius. The single interactive/action color is #B05A36 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #B05A36 — the single interactive color; only on things you click or must notice, never large fills.
• primary, link are all #FEF9EF — one role, not several (the action color).
• accent, button_bg are all #B05A36 — one role, not several (the action color).
• accent #B05A36 — 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.
• secondary #F5EEE1 — 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.

# Function Health — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#FEF9EF` |
| surface | `#F1ECE3` |
| border | `#DEDAD2` |
| text | `#2A2B2F` |
| text_muted | `#7A7977` |
| primary | `#FEF9EF` |
| accent | `#B05A36` |
| link | `#FEF9EF` |
| secondary | `#F5EEE1` |
| button_bg | `#B05A36` |
| button_text | `#FEF9EF` |

**Using these colors**

- **Action color** `#B05A36` — 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 `#FEF9EF` — one role, not several.
- `accent`, `button_bg` are all `#B05A36` — one role, not several (your action color).
- **accent** `#B05A36` — 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.
- **secondary** `#F5EEE1` — 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.
- **Page coverage** (full-page screenshot pixels): `#2E241A` 16.5% · `#7D7E7F` 16.4% · `#AFA9A4` 16.1% · `#504635` 12%

## Typography

- Heading: **Financier Display** _(free fallback: Newsreader)_
- Body: **Arial**
- Mono: **Fragment Mono** _(measured)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 80px / 300 · lh 72px |
| h2 | 64px / 300 · lh 64px |
| h3 | 45px / 300 · lh 45px |
| body | 16px / 300 · lh 24px |
| small | 15px / 600 · lh 23px · tracking -0.05px |
| eyebrow | 11px / 400 · tracking 1.1px |

- Weight ladder: 300 · 400 · 600 — use these exact measured weights, not the 400/600 defaults.

> **Fonts —** Financier Display may be proprietary — safe free fallback: Newsreader (Google Fonts). Arial — system font, no web load needed.

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 2px, 4px, 8px, 12px, 16px, 20px, 24px, 25px, 32px, 40px — snap all gaps/padding to these
- section rhythm: 99px top/bottom padding per section (measured)

## Radius
- base: 12px
- button: 36px
- card: 12px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#B05A36` / `#FEF9EF` | 1px solid rgb(176, 90, 54) | 36px | 0px 20px 0px 20px | 600 14px / -0.05px | none |
| secondary | `#FEF9EF` / `#B05A36` | 1px solid rgb(254, 249, 239) | 9999px | 12px 25px 12px 25px | 600 16px | none |

**States (measured, not guessed)**

- primary hover: border `1px solid rgb(143, 70, 42)`
- primary focus: border `1px solid rgb(143, 70, 42)` · outline `2px solid rgb(7, 26, 36)`
- transition: `color 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) 0px 0px 0px 0px`
- card: `rgba(0, 0, 0, 0.1) 0px 4px 30px 0px`
- overlay: `rgba(42, 43, 47, 0.14) 0px 18px 40px 0px`

## Motion
- durations: 180ms (dominant) · 200ms · 240ms
- easings: `ease` (dominant) · `cubic-bezier(0.4, 0, 0.2, 1)`
- animated properties: opacity, color, background-color, backdrop-filter

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)

_…and 108 more measured on the page._

Prefer these names when extending their system — it's the brand's actual vocabulary.

## Layout (measured)
- container max 1250px
- nav: 112px relative

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 940 | 858 | — | — | 99/99 | — |
| 1798 | 678 | — | — | 99/99 | — |
| 2477 | 1305 | — | — | 99/99 | — |
| 3782 | 898 | — | — | 80/99 | — |
| 3862 | 174 | — | — | 0/64 | — |
| 4680 | 294 | — | — | 80/96 | — |

## Motion choreography (measured)
Load order: `div.tracked_marquee-track`×2 @0ms → `div.logocarousel_track` @0ms → `button.medical-board__nav` @325ms → `button.medical-board__nav` @325ms → `button.medical-board__nav` @325ms → `button.medical-board__nav` @325ms
- `div.ketch-fixed` — transform translateY(900px)→translateY(0px) — 400ms ease
- scroll reveal: 7 elements rest at opacity 0, translateY(-4px), animate in over 400ms (1 revealed during the drive).
- overlay dialog (auto-opened): panel #F5EEE1 · r 12px · border 1px solid rgba(42, 43, 47, 0.14) · shadow rgba(42, 43, 47, 0.14) 0px 18px 40px 0px
  - exit: transform from translateY(0px) · 180ms ease

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

## Components (measured)
- card ×3: pad 40px 20px 40px 20px · r 12px · bg #F5EEE1
  - hover: font-weight `300` · letter-spacing `normal`
- link: #B05A36 · underline

## Responsive (measured)
- breakpoints: 380px · 480px · 768px · 900px · 960px · 1024px
- mobile (390px): hero 57px · body 16px · nav: inline

## 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.
