/*
  Purpose: visual system for the aipromo.io landing (web/index.html), rebuilt 2026-10-25 to the owner
  reference "Küresel Yapay Zekâlı Alışveriş Asistanı.png".
  Responsibility: tokens, header, hero (intro, illustrated scene, chat preview), feature strip, global
  section, popular categories, how it works, FAQ, footer, sign-in panel, motion and responsive rules.
  Geometry: the hero scene is laid out on the reference's 1122 px frame; scene positions are percentages
  of that frame so the composition scales instead of reflowing on desktop widths.
  Consumers: web/index.html; state classes .is-open, .is-new, .is-typing are set by web/js/site.js.
