/* ============================================================
   Account pages (login/signup) — minimal by design (Phase A).
   Reuses shared/css/hub.css's tokens and header/footer chrome
   verbatim (both stylesheets are linked together on these pages);
   this file only adds what hub.css has no reason to carry itself:
   a centered card and real form controls. The distinct platform
   brand for account pages is a later phase — see CONTRACT.md's
   Backend section.
