/* ==========================================================================
   Wondermaths - illustrated five-world selector for the five world pages.
   Replaces the old .realm-switcher pill nav. Desktop renders the approved
   homepage board (assets/home-20260924/worlds.webp, 1536x1024) with five
   full-tile links; below 1100px it renders the five native world cards from
   the same homepage assets. Loaded after worlds-living.css. Colours come
   from the portal / world tokens (--wl-*), so the Magic Realm page keeps its
   own purple without a separate rule.
