/* Anime Lab — hub chrome.
   Only the landing and franchise pages use this. Each scene keeps its own
   styling entirely; the hub deliberately does not try to unify thirteen
   different art directions, it just frames them.

   Dark and restrained on purpose: every scene behind these cards is loud, so
   the shell around them should not compete. Colour arrives only through
   --accent, set per franchise. */
