/**
 * Top-level route table. Every authenticated section is nested under one
 * `RequireAuth` + `AppLayout` parent route (sidebar chrome + `/auth`
 * guard applied once, not per-page — see {@link AppLayout}); `/login` and
 * `/signup` redirect an already-logged-in visitor to `/` instead (see
 * {@link RedirectIfAuthenticated}). Anything else falls back to `/`, which
 * itself redirects to `/login` if needed.
 *
 * `/parametres/*` (compte/préférences alimentaires/foyer/préférences
 * utilisateur/crédits) are the settings pages, reachable from the sidebar's
 * bottom "Paramètres" menu and the account menu (see `AppLayout`) — nested under
 * `AppLayout` like every other authenticated section. `/foyer` is the old,
 * pre-split combined page's path; it now just redirects to
 * `/parametres/foyer` so an existing bookmark/link keeps working.
 *
 * `/onboarding/*` (regime/foyer/sources/allergens, in that order) is also
 * `RequireAuth`-gated — reached right after signup, once a session already
 * exists — but deliberately its own top-level route group, *not* nested
 * under `AppLayout`: a focused, distraction-free wizard with no sidebar,
 * same full-page-card language as `/login`/`/signup` (see `onboarding.scss`).
 * `/onboarding/sources` is conditional — only reached when the `foyer` step
 * created/joined a household (see `OnboardingHouseholdPage`'s `goToNextStep`);
 * skipped otherwise, straight to `/onboarding/allergenes`.
 *
 * `/admin/*` is the internal admin surface (metrics, monitoring, correction
 * triage, off-catalog ingredient review). It's its own top-level group,
 * wrapped in {@link AdminAuthProvider} so the `GET /admin/api/auth/me` session
 * probe only runs under `/admin` — the admin session (cookie `admin_session`,
 * `ADMIN_JWT_SECRET`) is entirely separate from the end-user one, so this is
 * never nested under `RequireAuth`. `/admin/login` is the only
 * unauthenticated admin route; everything else sits under `RequireAdmin` +
 * `AdminLayout`.
