react-composition-structure

React and React Native file-system architecture patterns that scale. Use when restructuring component folders, route-bound domain modules (a calendar, cart, or checkout surface placed under `components/`, `screens/`, or any repo tree — not a literal `features/` directory), `index.ts` export boundaries, naming conventions, colocated `*.data.ts` files, or translating composition patterns into stable repo structure. Triggers on compound component folders, route-bound module folders, public API cleanup, and bad-vs-good file organization examples.
