   call-numbers.css  —  Casino / game-show theme for the BINGO caller

   Bootstrap + the shared bingo-cards.css for this page.
   No JS hooks are renamed — this is a re-skin only.

   Phase 1 — foundation: design tokens, felt table, header/nav,
   typography, buttons, base panels. (Hero ball + pattern board and
