/* =====================================================================
   META-STYLE THEME  —  Michelle Jung Piano Studio
   Implements DESIGN-meta.md: white canvas, full-bleed photography,
   pill buttons (black marketing / cobalt commerce), generous rounding,
   clean geometric type, tight three-tier hierarchy.
   Loaded AFTER css/styles.css so these rules win the cascade.
