   Cross-promo house ad → SurWill (surwill.ge)

   SurWill is our sibling project: "save items from every shop in one place".
   This band is an unpaid cross-promo (not part of the moderated `ads` app
   inventory), so it's plain site chrome included above the footer.

   It deliberately carries *SurWill's* identity — near-black "ink" surface,
   warm "cream" text, square brutalist edges — so inside Kadnieri's white
   editorial pages it reads as a distinct product by the same maker.

   All class names are prefixed `xpromo-` to avoid collisions with site CSS.
   Motion (the sliding wordmark marquee) is decorative and is disabled under
   prefers-reduced-motion.
