/* ============================================================
   VegasBet - Promo activated modal ("Reward Received", table 1)

   Markup: templates/_promo_modal.html. Filled by main.js showPromoModal.
   One card for both promo types; the copy, the figure, the icon and the
   worked example are what change.

   The header is the auth hero's layer stack (auth-hero.css) shrunk to a
   card: photo -> purple tint masked off the face -> glow -> a mask that
   dissolves the whole stack into the card. Same rules as there: every
   loop moves transform or opacity only, none cycles under 4s, and the
   photo's one-shot intro is the only animated `filter`.
