Decoded design system

DeepSeek Mobile's decoded design system: background #FFFFFF, text #0F1115, accent #8B8B8D, link #475569, primary #8B8B8D; type scale h1 30px / h2 24px / body 14px; 4px spacing base; 12px base radius. The single interactive/action color is #8B8B8D — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

# DeepSeek Mobile — Design System

> light, consumer, high — deep decode (measured live)

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#F0F0F0` |
| border | `#DBDBDB` |
| text | `#0F1115` |
| text_muted | `#6A6B6D` |
| primary | `#8B8B8D` |
| accent | `#8B8B8D` |
| link | `#475569` |
| button_bg | `#8B8B8D` |
| button_text | `#475569` |

**Using these colors**

- **Action color** `#8B8B8D` — 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`, `button_bg` are all `#8B8B8D` — one role, not several (your action color).
- **accent** `#8B8B8D` — 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.
- **link** `#475569` — inline text links and link-styled controls.
- **Page coverage** (full-page screenshot pixels): `#DDE9F9` 47.7% · `#F7F9FB` 40.8% · `#7798E5` 11.5%

## Typography

- Heading: **quote-cjk-patch** _(free fallback: Newsreader)_
- Body: **quote-cjk-patch** _(free fallback: Newsreader)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 30px / 500 · lh 36px |
| h2 | 24px / 500 · lh 36px |
| h3 | 20px / 500 · lh 28px |
| body | 14px / 400 · lh 20px |

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

> **Fonts —** quote-cjk-patch may be proprietary — safe free fallback: Newsreader (Google Fonts).

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 4px, 8px, 12px, 20px, 24px, 28px, 32px, 40px, 48px, 80px — snap all gaps/padding to these

## Radius
- base: 12px
- button: 6px
- card: 6px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `rgba(0, 0, 0, 0)` / `#475569` | 2px solid rgba(255, 255, 255, 0) | 6px | 0px 0px 0px 0px | 400 15px | none |
| secondary | `rgba(0, 0, 0, 0)` / `#475569` | 2px solid rgba(255, 255, 255, 0) | 6px | 0px 0px 0px 0px | 400 14px | none |

**States (measured, not guessed)**

- primary hover: color `#679EFE`
- primary focus: box-shadow `rgb(57, 100, 254) 0px 0px 0px 2px`
- transition: `color 0.2s cubic-bezier(0.4, 0, 0.2, 1)`

## Shadows (elevation)
- subtle: `rgb(236, 239, 242) 0px 0px 0px 1px, rgba(0, 0, 0, 0.02) 0px 2px 4px 0px, rgba(0, 0, 0, 0.02) 0px 12px 48px 0px`
- card: `rgba(0, 0, 0, 0.01) 0px 2px 4px 0px, rgba(0, 0, 0, 0.02) 0px 12px 24px 0px`

## Motion
- durations: 200ms (dominant) · 300ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant)
- animated properties: color, box-shadow, opacity, text-decoration-color

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

## Layout (measured)
- container max 1152px · common grid: 6-col

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 0 | 783 | 7 | 112 | 0/0 | — |
| 783 | 388 | 6 | 40 | 0/0 | — |

## Components (measured)
- link: #0F1115 · underline

## Responsive (measured)
- breakpoints: 768px
- mobile (390px): body 14px · 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.
