/* ============================================================
   /locked — «اپل آیدی قفل شد؟», the Instagram landing page.
   Nearly every visitor arrives from a reel, on a phone, so it is
   built phone-first: one column, big tap targets, and a sticky
   button once the hero is gone. The hero is the same midnight +
   indigo glow as the story poster, so the reel and the page feel
   like one thing. Everything else uses the site's own tokens and
   follows light/dark with them.
