/* image-trail runtime — full-bleed pointer photo trail hero.
   Alles gescoped unter .ms-image-trail (kein globales CSS, keine festen IDs).
   Das Content-Window-Panel (.hud*) stammt aus _shared/hero-chrome.css —
   der Preview-Host und die Demo binden es selbst ein (BB-Adapter enqueuet
   es als geteiltes Asset), damit file:// und Builder-Kontexte funktionieren.
   Die .content__img*-Klassen sind der DOM-Vertrag der ImageTrail-Klassen
   (React-Bits, oben in runtime.js inline) und bewusst unveraendert. */
