 - **Frontend en español**: copy de UI, comentarios y textos en español.
+- **Base de datos**: todas las tablas usan **snake_case** vía `@@map` en `prisma/schema.prisma` (p. ej. `User` → `users`, `WaitlistEntry` → `waitlist_entries`). Al agregar un modelo nuevo, incluir siempre `@@map("nombre_tabla")`.
 - **Tailwind v4** con tokens en `@theme` dentro de `apps/web/src/index.css` (p. ej. `--color-accent: #1e90ff`). Se usan como clases auto-generadas: `text-accent`, `bg-success-soft`, etc. Radius por defecto `0.75rem` (`rounded-xl`).
 - **Router NO es file-based** (aunque `stack.md` lo diga): las rutas se declaran manualmente en `apps/web/src/router.tsx` con `createRoute` + `addChildren` y se registran vía module augmentation. **Cada vista nueva debe añadirse ahí.**
 - Nav (Inicio/Grupos/Cobros/Ajustes) vive en `apps/web/src/components/layout/nav-items.ts`; es la fuente única para `BottomNav` (móvil) y `Sidebar` (desktop) — no dupliques la lista.
