/* ==========================================================================
   Funnel UI — light theme, hand-tuned
   Contract: class names are rendered by assets/js/app.js — do not rename.
   Theming: app.js sets --accent on :root per funnel.
   Color psychology: accent = action only; green = safety/guarantee;
   amber = urgency/scarcity; red = loss (anchor price, errors); ink on
   warm white everywhere else. Minimal chrome, satisfying motion.
