   app.css — VCalendar design system (light theme)
   ────────────────────────────────────────────────────────────────────
   Crisp white surfaces, violet as a disciplined accent, and a faint
   dot-grid "time grid" signature that nods to the booking calendar.
   One shared shell for every page; public studio pages override
   --accent at runtime from the studio's own brand colour.
