/* ============================================================
   Bet Assist Hub — Shared Component Classes
   Semantic shell classes consumed by both Django template
   partials and React component adapters. Each class uses
   tokens from theme.css so a single edit propagates everywhere.

   Color vars use Tailwind v4 convention: var(--color-*)
   Non-Tailwind vars keep the --bah- prefix.
   Opacity: color-mix() replaces the old RGB-triplet hack.
