/* ==========================================================================
   Default theme — site chrome (public shell, auth, docs, maintenance).
   Complements css/core.css (Bootstrap 5 + Default core). Built on core tokens:
   --bs-primary, Public Sans, [data-bs-theme="light"|"dark"].

   Default's shape language: smaller radii and flatter surfaces than a Material
   marketing theme, so --pub-radius is deliberately tighter and the shadows are
   subtle — cards read as bordered panels rather than floating material.
