   SurfEnglish cross-promotion — pinned announcement bar + promo section.
   Markup, copy and locale handling live in js/surfenglish-promo.js; this file
   only styles what that script injects. Brand tokens mirror surfenglish.app
   (dark "oceanic liquid glass") so the block reads as a SurfEnglish card
   sitting inside the light WordByWord site.
