   Interactive "How it works" demo — a faux order flow that auto-plays.
   Replicates the real order forms (Amount → Comfort → EA → Status) with an
   animated cursor + typing. Pure presentational; no business logic.
   Palette mirrors the real order flow (coins.css): bg #1a1e22, panels
   #22262c / #272e36, accent green #48ff91, slider purple #726bff.
