/* ============================================
   Promo Banner (generic, campaign-agnostic)
   ============================================
   Styles for the banner rendered by /js/promo-banner.js into the
   #promo-banner-root slot. Everything is namespaced under .pti-promo-banner
   so it cannot clash with existing site CSS. Colors and fonts come from the
   site's existing :root variables (style.css) with safe fallbacks — nothing
   campaign-specific is hardcoded here, so the file is reusable as-is for
   future campaigns.

   The empty #promo-banner-root slot renders nothing and takes no space, so
   it is safe to leave in every page permanently between campaigns. */
