Backend conventions for the Hono server app — module layout, routers, middleware, cron jobs, and BullMQ workers. Use when creating or refactoring any backend route, worker, cron job, or server module in apps/server/src/.

Frontend conventions for the Vite client app — component colocation, page structure, PageContainer, Breadcrumb, and PageHeader layout, shared components, and server data fetching. Use when creating or refactoring components or pages, organizing frontend files, or fetching data from the server.

ALWAYS ACTIVE. Enforces a strict no-direct-useEffect rule in React and React Native code. Never write useEffect directly — use derived state, event handlers, useMemo, useSyncExternalStore, data-fetching libraries, key-based resets, or useMountEffect instead. Triggers on all React component code: writing new components, editing existing ones, reviewing code, fixing bugs, or refactoring. Also triggers when user mentions useEffect, side effects, data fetching, state sync, or component lifecycle.
