Decoded design system

Tana's decoded design system: background #FBFBFB, text #202020, accent #0C0805, link #0C0805, primary #ECE4D4; type scale h1 72px / h2 48px / body 16px; 4px spacing base; 12px base radius. The single interactive/action color is #0C0805 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #0C0805 — the single interactive color; only on things you click or must notice, never large fills.
• accent, link, button_bg are all #0C0805 — one role, not several (the action color).
• accent #0C0805 — 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.
• primary #ECE4D4 — a neutral UI color (chips, tags, icon fills, chrome), not the action color (action = #0C0805).
• secondary #D88A82 — 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.

# Tana — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#FBFBFB` |
| surface | `#EDEDED` |
| border | `#DADADA` |
| text | `#202020` |
| text_muted | `#737373` |
| primary | `#ECE4D4` |
| accent | `#0C0805` |
| link | `#0C0805` |
| secondary | `#D88A82` |
| button_bg | `#0C0805` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#0C0805` — 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`, `button_bg` are all `#0C0805` — one role, not several (your action color).
- **accent** `#0C0805` — 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.
- **primary** `#ECE4D4` — a neutral UI color (chips, tags, icon fills, chrome), not the action color (action = #0C0805).
- **secondary** `#D88A82` — 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): `#F9F5F2` 54.5% · `#EBDACA` 21.6% · `#7A5830` 12.3% · `#C5A77A` 11.6%

## Typography

- Heading: **Source Serif 4** _(free fallback: Newsreader)_
- Body: **Inter**

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 72px / 500 · lh 76px · tracking -3.24px |
| h2 | 48px / 500 · lh 53px · tracking -2.16px |
| h3 | 32px / 400 · lh 37px · tracking -1.44px |
| body | 16px / 400 · lh 22px |
| small | 15px / 400 · lh 22px |
| eyebrow | 11px / 400 · tracking 0.88px |

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

> **Fonts —** Source Serif 4 may be proprietary — safe free fallback: Newsreader (Google Fonts). Inter — free, on Google.

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 2px, 4px, 6px, 8px, 10px, 12px, 14px, 16px, 18px, 23px — snap all gaps/padding to these
- section rhythm: 44px top/bottom padding per section (measured)

## Radius
- base: 12px
- button: 14px
- card: 16px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#0C0805` / `#FFFFFF` | none | 14px | 14px 28px 14px 28px | 500 17px | none |
| secondary | `rgba(0, 0, 0, 0)` / `#0C0805` | none | 14px | 8px 18px 8px 18px | 500 14px | color(srgb 0.0470588 0.0313726 0.0196078 / 0.35) 0px 0px 0px 1px inset |

**States (measured, not guessed)**

- primary hover: background `#000000` · transform `matrix(1, 0, 0, 1, 0, -1)`
- primary focus: outline `2px solid rgb(12, 8, 5)`
- secondary hover: box-shadow `rgba(0, 0, 0, 0) 0px 0px 0px 1px inset` · color `#FFFFFF`
- transition: `transform 0.12s ease`

## Shadows (elevation)
- subtle: `rgba(11, 17, 32, 0.06) 0px 1px 2px 0px, rgba(11, 17, 32, 0.06) 0px 6px 16px 0px`
- card: `rgba(20, 22, 36, 0.04) 0px 1px 2px 0px, rgba(20, 22, 36, 0.1) 0px 6px 18px -12px`
- overlay: `rgba(20, 22, 36, 0.18) 0px 6px 16px -8px, rgba(20, 22, 36, 0.28) 0px 40px 96px -28px`

## Motion
- durations: 120ms (dominant) · 160ms · 150ms
- easings: `ease` (dominant) · `cubic-bezier(0.16, 0.84, 0.44, 1)`
- animated properties: transform, opacity, background-color, color

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

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

## Layout (measured)
- container max 1480px · common grid: 3-col
- nav: 72px sticky

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|

| 571 | 877 | — | — | 16/96 | — |
| 1448 | 253 | — | — | 0/0 | — |

| 3302 | 928 | 2 | 152 | 192/192 | 58/42 |

## Motion choreography (measured)
Load order: `span.HeroCta_reassurance__YQf`×3 @0ms → `div.ThreePillars_actionPill_`×5 @0ms
- `div.ThreePillars_actionPill_` ×5 — opacity 0→1 — 540ms cubic-bezier(0.16, 0.84, 0.44, 1)
- `span.HeroCta_reassurance__YQf` ×3 — opacity 0→0.85 · transform translateY(4px)→translateY(0px) — 7500ms ease-in-out · loops
- stagger: `span` ×3 — 2500ms apart

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

## Components (measured)
- card ×3: pad 44px 44px 44px 44px · r 32px · bg rgba(0, 0, 0, 0)
  - hover: font-weight `400` · letter-spacing `normal`
- link: #FFFFFF · underline

## Responsive (measured)
- breakpoints: 520px · 640px · 700px · 768px · 1000px · 1024px
- mobile (390px): hero 40px · 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.
