/* ==========================================================================
   Tansi Booking Pages — public /book/{Token} and /book/cancel/{Token}
   --------------------------------------------------------------------------
   A two-column "promo + booking card" page in the tansi.app voice:
   the left column tells the visitor who Tansi is, the right column is the
   scheduler. Everything is scoped under .booking-shell.

   These pages render under EmptyLayout, whose bare <MudThemeProvider /> emits
   MudBlazor's DEFAULT palette (purple primary). The scope below re-points the
   Mud palette vars the picker/buttons read at the Tansi brand tokens from
   app.css (:root --primary etc.), so this page matches the app without
   touching the other public pages.

   Motion follows the apple-design house rules: feedback on pointer-down,
   critically-damped curves (no overshoot on things that just appeared),
   transform/opacity only, and every animation has a reduced-motion twin.
