/* ======================= BOOKING (#schedule) — shared by every root =======================
   Mirrors public/schedule-widget.js: a modal, one fixed panel size on every step,
   services -> [staff] -> date (six-week calendar) -> time -> contact -> success.
   Root knobs (same names as the widget's data-sched-theme):
     --bk-radius        modalRadius  sharp | soft | round
     --bk-chip-radius   chipStyle    square | pill
     html[data-bk-back] backButtonStyle  text-arrow | icon-arrow
   Colors and fonts come from the root's own tokens. Icons use the root's Material Icons family
   (html[data-icons], same map as MATERIAL_ICON_STYLE_MAP in generation-prompt-builder.ts). */
