 Notes:
 
+- Linaria 7 requires Node.js 20+ (aligned with WyW 1.x).
 - If you import JSON from code that is evaluated by WyW, add `.json` to `extensions` and ensure `.json` is ignored by evaluation rules (so it's parsed as JSON, not by Babel).
 - Rollup users: WyW 1.x serializes `transform()` by default (`serializeTransform: true`). If you hit Rollup "Unexpected early exit" (unresolved plugin promises / deadlock during resolve), set `serializeTransform: false` (see `examples/rollup/rollup.config.mjs`).
 - WyW 1.x promotes fully-statically-evaluatable modules to `only: ['*']` and can re-evaluate modules when cached exports are incomplete (cached export values might not be reused).

 Linaria 7 updates the WyW toolchain (`@wyw-in-js/*`) to `^1.0.0` (stable). This affects build-time evaluation (CSS extraction) and can surface previously hidden issues in evaluated modules.
 
 - Review https://wyw-in-js.dev/stability for the evaluation model, common pitfalls, and performance guidance.

 - If you rely on WyW cache internals, note that WyW 1.x can promote fully-statically-evaluatable modules to `only: ['*']` and may re-evaluate modules when cached exports are incomplete.
