# Gradient Atelier

## Overview

细渐变与轻字重，像一张印得很好的收据。 整体气质是 日常应用适中、错落不对称、动效 流畅 CSS 动效。品牌语气：refined / luminous / thin。密度 4/10，变化 6/10，动效 6/10。 材质：细渐变只做氛围，控件保持实色。字重偏轻。

How to use: 把本文件放到仓库根目录。在 Cursor / Claude Code / Codex 提示词中写：请阅读 DESIGN.md 并严格遵守其中的 tokens 与 Do/Don't。

## Colors

Semantic roles for the light theme. Keep a single accent; do not introduce a second brand hue.

- **primary** (`#635BFF`)
- **secondary** (`#6B7280`)
- **tertiary** (`#0A2540`)
- **background** (`#FFFFFF`)
- **surface** (`#F6F9FC`)
- **outline** (`#E6EBF1`)
- **muted** (`#687078`)
- **success** (`#0D9488`)
- **warning** (`#D97706`)
- **error** (`#DF1B41`)
- **onPrimary** (`#F4F4F5`)
- **onSecondary** (`#F4F4F5`)
- **onTertiary** (`#F4F4F5`)
- **onBackground** (`#18181B`)
- **onSurface** (`#18181B`)

## Typography

Hierarchy comes from weight and size, not from shouting. Body line length stays near 65 characters.

- **h1**: Geist 600 / 40px / 1.12 / -0.03em
- **h2**: Geist 600 / 28px / 1.2 / -0.02em
- **h3**: Geist 600 / 20px / 1.3 / -0.01em
- **body**: Geist 400 / 16px / 1.55 / 0em
- **label**: Geist 500 / 13px / 1.3 / 0.02em
- **caption**: Geist 400 / 12px / 1.4 / 0em
- **mono**: "JetBrains Mono" 500 / 13px / 1.45 / 0em

## Layout

Spacing scale: xs=4px, sm=8px, md=16px, lg=24px, xl=32px, 2xl=48px, 3xl=64px.

iOS：触控目标 ≥ 44pt，尊重 Safe Area 与 Dynamic Type，图标用 SF Symbols，导航使用 Large Title / 分组列表。

Web：移动优先，<768px 单列，正文 ≥ 16px，标题用 clamp()，容器 max-width 约 1120–1400px，全高区块用 min-h-[100dvh]。

Every element occupies its own spatial zone. No overlapping hero text. Collapse multi-column layouts below 768px.

## Elevation & Depth

- sm: `0 1px 2px rgba(24,24,27,0.06)`
- md: `0 8px 24px rgba(24,24,27,0.08)`
- lg: `0 18px 48px rgba(24,24,27,0.12)`
- surface: `flat`
- recipe: 细渐变只做氛围，控件保持实色。字重偏轻。

Tint shadows toward the background hue. High-density layouts may replace cards with hairline dividers.


## Shapes

Radius scale: sm=6px, md=8px, lg=14px, xl=999px, full=999px.

## Components

- **导航栏** (`web.navbar` / default / md): 桌面横导航含 logo、带图标的链接和一个主 CTA。
- **Hero** (`web.hero` / split / lg): Hero 使用 split 布局，最多一个主 CTA，禁止「Scroll to explore」。
- **定价表** (`web.pricing` / default / md): 最多突出一个方案，价格用等宽字体。
- **指标块** (`stat` / default / md): 数字用等宽字体，标签用大写弱化。
- **列表行** (`list-item` / chevron / md): 行高至少 44pt，标题 + 说明，右侧可放 chevron。
- **列表行** (`list-item` / chevron / md): 行高至少 44pt，标题 + 说明，右侧可放 chevron。
- **进度条** (`progress` / default / md): 线性进度，填充色为 primary。
- **页脚** (`web.footer` / default / md): 页脚克制，链接分组清晰。

## Do's and Don'ts

### Do
- Use semantic color tokens, never raw hex in components.
- Keep a single accent; hierarchy comes from type weight and space.
- Define default, hover, focus-visible, pressed, disabled, and loading states.
- Meet WCAG 2.2 AA contrast for body text and interactive labels.
- Touch targets are at least 44×44pt on iOS and 44px on web.

### Don't
- Do not use Inter as the display face for premium work.
- Do not use pure black #000000 for large surfaces.
- Do not add neon outer glows or custom mouse cursors.
- Do not ship three equal feature cards as the default layout.
- Do not hide focus rings or drop below AA contrast.
