/* =====================================================================
   Premium auth design system — shared by /login and /register only.
   Loaded AFTER app.css so it refines (never fights) the app theme.
   All rules are scoped to the auth pages (.auth-* / body.auth-body), so
   dashboard pages that never load this file are unaffected.
   Dark mode follows the app: app.js sets html[data-bs-theme="dark"].
