/* ---- Promo card ----------------------------------------------------------
   A CORNER CARD, not a full-screen curtain. A full-screen overlay on arrival is
   what Google classifies as an intrusive interstitial — a documented mobile
   ranking negative — which is the same reason the intro splash is constrained
   the way it is (CLAUDE.md §15). This never covers the content and never
   blocks a click on the page behind it. Don't promote it to a modal. */
