/* ============================================================
   Ad placeholders — stub system for free-tier monetization preview.
   Real ad network (AdMob in Capacitor, AdSense in webview) plugs into
   the same DOM hooks later. Today these render branded placeholder
   slots so we can validate layout + UX before any AdSense compliance
   review (EI's site is in AdSense Ready window — keep zero real ads
   in app until web is approved).

   All slots gate on `body.is-premium` — hidden for Premium subscribers,
   visible for anonymous + Free users.
