   ANANTAR ULTIMATE — migrated components, re-skinned to the
   Infinity black/gold theme.

   These classes originate from the old anantarultimate.com
   single-page site. Their LAYOUT is preserved; every blue/purple
   accent has been remapped to the Infinity palette so the merged
   site reads as one design language.

   Depends on style.css for the root variables:
     --bg-dark #070709  --bg-surface #121218
     --text-main #fff   --text-dim #A0A0A8
     --accent-blue #2CB1F3  --accent-gold #D4AF37
