/* ═══════════════════════════════════════════════════════════════════════
   /advertise/ — how advertising on Mega Tickets USA works (the explainer
   in front of the reservation page /mega-sponsors/advertise/).

   Kit first: /marquee/site.css (tokens, type, buttons, cards, stats, feats,
   stubs, checks, callouts, FAQ, closing band) and the sponsor kit
   /mega-sponsors/advertise/advertise.css (billboard mocks .adv-mock/.adv-bb,
   radio cards .adv-opt/.adv-slot, .adv-price/.adv-sum/.adv-lock, notes,
   .adv-file, .adv-foot). Only what this page needs and neither has lives
   here. Behaviour: ./explainer.js. Light only (the site has no dark mode);
   literal px on the project's 2px grid, as the kit writes them.
