   CAIRN PROMO (2026-10-22)
   The Cairn spotlight on /systems and /services reuses the shared
   .snapline-spotlight markup (like Tembr), recoloured to Cairn's lichen.
   The slim .cairn-bar is the homepage banner.
   Kept out of style.css on purpose: loaded only by the three pages that
   show Cairn, linked from their body like services-film.css.
