/* ==========================================================================
   Koby's Legacy — Memorial Website Stylesheet
   --------------------------------------------------------------------------
   A dignified, warm, calm memorial for the Sephardic Jewish liturgical
   recordings of Koby Benlolo ז״ל.

   Design notes:
   - Mobile-first: base styles target small screens; media queries enhance
     for wider viewports.
   - No web fonts / @font-face / external assets — fully offline, works on
     both file:// and a normal web server.
   - All theme colors live in :root custom properties so the family can
     re-theme the whole site from one place.
