/* ────────────────────────────────────────────────────────────────
   Star-field mode switcher

   A button + dropdown menu in the hero's top-right that lets a visitor pin
   the background game mode instead of taking the random one. Built by
   js/main.js, which only inserts it on pages that actually have a hero
   star field.

   Deliberately quiet until hovered or focused: this sits on a marketing
   hero and must never compete with the primary CTA.
