   Booking — Tabletop Teachings
   Loaded by index.html after css/style.css. Every colour comes from the
   tokens in style.css; the only new value is a distinct error red, because
   --accent is already the "click me" colour and must not double as a warning.

   Contents
     NOTE: .step and .steps belong to the "how it works" component in
   style.css (.step sets max-width:18rem and text-align:center). The booking
   flow uses .bk-step / .bk-steps instead. Don't rename them back.
