/* ==========================================================================
   Mobile presentation layout — <768px rules for the story presentation surface
   Targets: .presentation-root, .pres-*, .deck-dots, .tww-*, .visual-frame,
            .media-item, .narration-transcript
   Desktop: no-op (all rules live inside the 767px media query)

   NOTE: the retired SwipePanel primitive's own rule blocks (.swipe-panel,
   .swipe-panel-column, .swipe-panel-dot(s)) were excised 2026-08-14 along with
   js/mobile/swipe-panel.js, which had zero callers. The presentation-layout
   rules below are LIVE and are why this file survives. A rename to
   mobile-presentation-layout.css is deliberately deferred (it churns sw.js,
   index.html and the library docs).
