/* ==========================================================================
   CAMPAIGN BOOKING SHEET — bespoke to promotional campaigns, not the
   general-purpose booking drawer.

   The opening choice screen is deliberately not built from app-style
   pricing cards (rounded tile, icon chip, colored discount pill, circular
   arrow CTA) — that's SaaS/fintech checkout language, not spa language.
   It's an editorial menu instead: eyebrow + headline live on the hero
   photo itself, the price sits quietly under a hairline rule, and each
   option is a plain full-width row separated by hairlines, the way a
   printed treatment menu presents two rituals.

   Later steps (calendar, time, guest info, payment) keep a cream canvas
   with white raised surfaces — that layered-depth pattern wasn't part of
   what needed to change and stays as-is.
