   BAMMB — restyled to match the BAMMBQM visual language: white surfaces,
   light-gray inset tiles, thin slate borders, indigo gradient accents.
   All existing class names from the original BAMMB stylesheet are preserved
   so the cshtml templates render unchanged — this file only swaps the look.
   Light-only (no prefers-color-scheme override) to mirror BAMMBQM.
