/* ═══════════════════════════════════════════════════════════════════
   /waitlist: the Join the waitlist page (templates/waitlist.html,
   static/js/waitlist.js). Approved design "page-waitlist", review 3,
   2026-10-07:
   1. hero: the navy band, a big globe behind the headline, the form beside;
   2. the stamped ticket, which replaces the form after a successful signup
      (built from a <template>; never on the page before that);
   3. Compare cohorts: two cohort cards, one over the other, split by a
      divider you drag, swipe or move with the arrow keys;
   4. closing: the running cohort's faces and live line.

   Scoped to .dfw. Layout and the page's own objects only: every field and
   button is the shared standard in static/css/df-forms.css (.dff-*), not
   restyled here. Every colour is a token from df-tokens.css (tests/
   test_theme_tokens.py forbids raw values here). The navy band uses the
   theme-stable --df-navy / --df-on-navy* tokens (never the footer ones).
