Bridge to or from external design systems via a role-based crosswalk.

通过基于角色的Crosswalk机制实现与外部设计系统的双向桥接。

Read
```
design-systems/interop-protocol.md
```
(Crosswalk Method, the three directions, headless-vs-styled guidance, verification).
Use the curated tables in
```
design-systems/crosswalk.md
```
for Material 3 / Apple HIG / Fluent 2 / Carbon / shadcn/ui / Radix. For others, derive a mapping with the Crosswalk Method (map by role/intent across 6 axes: color roles, type scale, spacing unit, radius, elevation, motion).
Choose the direction:
- FROM external → our tokens (adopt their look): re-point
```
semantic.*
```
  .
- TO external stack (our components on their foundation): theme their primitives with our tokens.
- Migrate: Audit → Map → Bridge (alias layer) → Verify, screen by screen.
Verify every mapped color pair for contrast (
```
scripts/contrast.py
```
/
```
a11y-audit
```
); confirm all 8 states + dark mode survive the mapping.

（内容包含Crosswalk方法、三种映射方向、无头/样式化组件选型指导、验证方式）。
针对Material 3 / Apple HIG / Fluent 2 / Carbon / shadcn/ui / Radix，可直接使用
```
design-systems/crosswalk.md
```
中预先整理的对照表。对于其他系统，使用Crosswalk方法推导映射关系：沿6个维度按角色/意图进行映射，分别为颜色角色、字体层级、间距单位、圆角、高程、动效。
选择映射方向：
- 从外部系统到我方token（采用外部系统的外观风格）：重新配置
```
semantic.*
```
  的指向。
- 接入外部技术栈（我方组件基于其基础构建）：使用我方token为其基础组件设置主题。
- 系统迁移：审计 → 映射 → 桥接（别名层） → 验证，逐屏幕推进。
验证环节：使用
```
scripts/contrast.py
```
/
```
a11y-audit
```
检查所有映射颜色对的对比度；确认全部8种状态 + 深色模式在映射后均可正常适配。
