- Any new runtime dependency should map to `StyleDependency` and invalidate only affected subscribers.
- Theme-aware changes must account for global theme, adaptive system theme, and `ScopedTheme`.
- CSS variables must keep lazy getter semantics on native because values may depend on current runtime state.
- Apps may compile Uniwind's source with React Compiler, for example a workspace-linked copy. Hooks that read runtime state during render, such as `useStyle` and `useUniwind`'s snapshot, opt out with `'use no memo'`; otherwise the compiler caches the read and returns stale values.
- Avoid introducing compatibility paths without known consumers or persisted behavior.
- Add tests for native, web, and types when changing public API or cross-platform behavior.

Add the web React Compiler regression test.

test:web runs only the standard Vitest configuration. It does not transform src with babel-plugin-react-compiler, so the existing web freeze test cannot detect this compiler-specific regression. Add a compiler-transformed web test path.

Review comment at @packages/uniwind/jest.config.native.js around lines 19 - 20:
Extend the Jest projects configuration to include a separate web React Compiler
test path in addition to the existing native project. Configure that web path to
transform src with babel-plugin-react-compiler so the existing web freeze
regression test executes under the compiler-transformed setup.
