Decoded design system

Sana's decoded design system: background #FFFFFF, text #0A1217, accent #1A73E8, link #0A0A0A, primary #FA8072; type scale h1 83px / h2 20px / body 16px; 4px spacing base; 8px base radius. The single interactive/action color is #0A1217 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #0A1217 — the single interactive color; only on things you click or must notice, never large fills.
• accent #1A73E8 — accent for emphasis — keep it rare on the page.
• primary #FA8072 — a brand color — but the call-to-action uses #0A1217, not this.
• link #0A0A0A — reads as a neutral UI color, not a link accent — verify against the reference (action = #0A1217).
• secondary #AADDFF — 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.

# Sana — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#F0F0F1` |
| border | `#DADBDC` |
| text | `#0A1217` |
| text_muted | `#676C6F` |
| primary | `#FA8072` |
| accent | `#1A73E8` |
| link | `#0A0A0A` |
| secondary | `#AADDFF` |
| button_bg | `#0A1217` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#0A1217` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- **accent** `#1A73E8` — accent for emphasis — keep it rare on the page.
- **primary** `#FA8072` — a brand color — but the call-to-action uses #0A1217, not this.
- **link** `#0A0A0A` — reads as a neutral UI color, not a link accent — verify against the reference (action = #0A1217).
- **secondary** `#AADDFF` — 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): `#FFFFFF` 56.9% · `#F0F0EE` 20.2% · `#372420` 10.6% · `#C5BF9D` 7.5%

## Typography

- Heading: **Sana Serif** _(free fallback: Newsreader)_
- Body: **Sana Sans** _(free fallback: Newsreader)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 83px / 400 · lh 79px · tracking -2.5px |
| h2 | 20px / 450 · lh 24px |
| body | 16px / 400 · lh 24px |
| small | 14px / 450 · lh 21px |

- Weight ladder: 400 · 450 · 500 — use these exact measured weights, not the 400/600 defaults.

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

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 2px, 4px, 6px, 8px, 10px, 12px, 16px, 18px, 20px, 24px — snap all gaps/padding to these

## Radius
- base: 8px
- button: 24px
- card: 24px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#0A1217` / `#FFFFFF` | 1px solid rgba(0, 0, 0, 0) | 24px | 8px 16px 8px 16px | 450 14px | none |
| secondary | `#0A1217` / `#FFFFFF` | 1px solid rgba(0, 0, 0, 0) | 3.35544e+07px | 6px 16px 6px 16px | 500 14px | none |

**States (measured, not guessed)**

- primary focus: outline `2px solid rgb(10, 18, 23)`
- secondary hover: background `rgba(10, 18, 23, 0.9)`
- transition: `all 0.2s ease`

## Motion
- durations: 400ms (dominant) · 100ms · 300ms
- easings: `ease` (dominant) · `cubic-bezier(0.16, 1, 0.3, 1)`
- animated properties: color, transform, opacity, background-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 |

| `--color-foreground-secondary-solid` | `#686d70` |
| `--color-background-tertiary-hover` | `#131314c2` |

_…and 84 more measured on the page._

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

## Layout (measured)
- common grid: 2-col
- nav: 36px relative

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 297 | 1116 | 2 | 18 | 0/0 | — |

## Motion choreography (measured)
Load order: `html` @0ms → `nav.navigationstyles__Styled` @15ms → `nav.navigationstyles__Styled`×3 @15ms → `div.navigationstyles__Naviga`×22 @15ms → `a.contentstyles__ButtonLin`×5 @15ms → `input.flex` @82ms

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

## Components (measured)
- input: h 38px · r 24px · border 1px solid rgba(10, 18, 23, 0.15) · bg #FFFFFF · placeholder rgba(0, 0, 0, 0.4)
  - focus ring: `1px solid rgba(0, 0, 0, 0.2)` — this exact construction, don't invent your own
- link: #0A1217 · underline
- disabled: bg rgba(0, 0, 0, 0.3) · text #FFFFFF

## Responsive (measured)
- breakpoints: 410px · 450px · 600px · 820px · 1400px
- mobile (390px): hero 44px · 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.
