   KAIROS HALO — public booking flow (book.html)
   ------------------------------------------------------------
   Only the pieces the shared design system (kairos-halo.css) doesn't
   already provide: appointment-type cards, the date calendar, the
   time-slot grid and the confirmation summary. Everything else reuses
   .kh-intake-wrap / .kh-progress / .kh-opt / .kh-success. Tuned to be
   excellent around 390px: large tap targets, single-column forms.
