Vite + React + TypeScript PWA, Google Identity Services for sign-in.

- [Zustand stores](./stores.md) - authStore, attendanceStore, adminStore, shiftPlanningStore, adminShiftStore, closureStore, adminPayrollStore — where all app logic lives
- [Dark modern design system](./design-system.md) - theme.css tokens/components, and this app's chart/nav/calendar additions

Notable components beyond the design system doc's list: `MonthCalendar`
(shared 7-column calendar grid), `ShiftPlanning` / `ShiftPlanManager`
(employee / admin shift planning UI built on it), `ClosureCard` (employee
month-end confirmation), `PayrollManager` (admin payroll workflow).
