/* Rootwave — haircare (fictional demo shop)
   BATCH FORMAT: routine-builder quiz — three quick questions (hair type,
   concern, routine length) drive a scoring recommender into a personalized
   routine with ingredient callouts and a discounted bundle add. Same
   centerpiece as Basin & Bloom, different palette/type/copy.
   Dark terracotta/copper theme, warm serif display type. */
