/**
* Shared layout for the auth pages (login, signup, forgot-password,
* reset-password). Provides the centered card frame so each page only
* has to render its own form.
*
* Also gates the routes: a signed-in user landing on any /login, /signup,
* etc. URL is bounced to /u/me (or the `next` query param if present).
* The check happens client-side because auth state lives in
* AuthProvider — there's no server-side cookie inspection here yet, and
* the redirect is purely cosmetic (logged-in users don't gain anything
* from re-seeing these forms, and signing in over an existing session
* would just no-op).
