Adding a Feature

1. Add a framework-neutral page in packages/mobile-ui/src; add lazy wrappers and explicit routes in all three apps. Keep native-only UI in its app.

2. Add English, Chinese and Japanese message keys and a translated meta.title. Use canonical paths for shared links; preserve each app's theme and safe-area layout.

3. Update openapi/schema.yaml, generate types, add a module under packages/api-client/src/modules, and implement the Mock handler. Use Query for remote data and Pinia only for client-owned state.

4. Cover behavior with unit/component tests and shared Playwright cases; run pnpm check and relevant E2E. Check shared packages independently, not only through app imports.

5. Update all five documentation locales, and add a changeset for public-package changes. Follow root AGENTS.md.

Start from the real catalog (CatalogPage.vue + queries.ts) or request example. Do not copy the old res.code/res.data examples or persist server lists in an order store.
