 Notes:
 
-- `npm run lint` targets package source/types plus scripts and TypeScript demo assets.
-- `npm run build:all` is expensive; use it when a change truly spans builds/docs/types/lint together.
+- `yarn lint` is read-only; `yarn lint:fix` explicitly fixes the same source/type/script range.
+- `yarn ci:check` runs strict toolchain/plan/lint/tests; `yarn ci:build` generates outputs and checks imports.
+- See `refactor/ci-setup.md` for CI and separate Pages deployment; remote activation is tracked separately.
+- `yarn build:all` is expensive; use it when a change truly spans builds/docs/types/lint together.
