/* =============================================================================
   sheen.css — shared "static gloss + restrained CTA shine" finish.
   Loaded by both the patient app and the admin portal.

   Design goals: a premium, polished feel without hurting a clinical/trustworthy
   tone or performance. Implementation is purely ADDITIVE — it uses pseudo-
   element overlays, so it never overrides element backgrounds or shadows. The
   animated shine is limited to primary (colored) buttons and is disabled under
   prefers-reduced-motion.
