   BOOK A DEMO CLASS — inner page
   Header/footer/consult are the shared components (folds.css), unmodified.
   Every section below uses a shape this design system hasn't used yet on
   another inner page, on purpose: a photo hero with an event-ticket card
   layered on top, an auto-scrolling course marquee where each card also
   bobs on its own timer, a diagonal step cascade (not a numbered list), a
   scattered badge cluster (not an icon grid), and an alternating
   conversation-style FAQ (not an accordion).
