/* =====================================================================
   Wedding Invitation Platform — shared styles
   Design system: fine-stationery ink/wine/brass palette, hairline rules
   instead of card shadows, Fraunces for display type + Public Sans for
   body/UI. Used by the admin-facing pages (login, dashboard, hall,
   super-admin) — invitation.html is guest-facing and has its own
   self-contained, differently-branded stylesheet inline.
