Frontend application entry

Only the application entry lives here; merchant, store and operator roots load independently.

Files and their individual responsibilities are listed in the generated source inventory. Each file starts with its contract summary.

Modules

• main.tsx: Browser bootstrap only; application selection and error recovery live in application/.

Verification

Run npm run build, npm test, npm run test:coverage and npm run architecture from frontend/. Coverage includes untested source files; a module in this folder is not automatically fully tested. See the root testing guide for backend integration and coverage limits.
