/* ═══════════════════════════════════════════════════════
   ARENA ENHANCEMENTS — post-handoff design iteration
   New component styles + a proper desktop layout, added per user feedback
   AFTER the initial verbatim integration. Kept separate from the untouched
   design (public/css/arena.css) and the pure scaffolding (arena-mount.css).

   Every rule is prefixed with `.arena-scope` so it (a) only affects Arena
   and (b) outspecifies the @scope-wrapped arena.css it refines — arena.css
   rules inside @scope keep their base specificity, so a `.arena-scope .x`
   selector here (one class higher) always wins. Loaded LAST.

   layout: a wider home column, multi-column card grids, centred modal sheets,
