/* ==========================================================================
   BackboneAI — Public marketing site
   Custom theme layered over Bootstrap 5 (CDN).

   Adapted from the Hogan Life theme. Palette retuned to the BackboneAI /
   Twin Tech Labs teal so the marketing site, the secure app, and the
   "Powered by Twin Tech Labs" callback all read as one brand family.
     --teal       #1387b1   primary  (Twin Tech Labs teal — also the app's)
     --teal-dark  #0f6d90   hover / depth
     --aqua       #18a5d6   bright accent
     --glow       #5cc6e8   highlight on dark surfaces
   Type: Fraunces (display, warm) + Inter (UI/body) — kept from the theme so
   the brand feels human and calm, not generic-SaaS.
