/* =============================================================================
   AUTH PAGES ON THE SHARED THEME — sign in / sign up, forgot + reset password,
   unsubscribe. Loaded after auth.css and before auth-light.css, so light mode
   keeps its own white card and pale panels.
   Same language as css/shared/theme.css: deep slate, solid surfaces, IBM Plex,
   one accent (cyan on dark, blue for actions), solid headings, no glow / lift /
   sheen on buttons.
