/* ============================================================================
   core_card_carousel — reusable equal-width card carousel (skeleton styles).
   Pairs with core_card_carousel.js, which clones the card set once and drives a
   seamless auto-scrolling / draggable loop. CSP-strict: external CSS only.

   Markup contract:
     .ce-carousel[data-card-carousel]
       .ce-carousel__viewport
         .ce-carousel__track   > one or more cards (any card class)
       .ce-carousel__controls  > [data-dir="prev"] [data-playpause] [data-dir="next"]

   Card LOOK stays with each page's own card class (.ce-model, .fa-core, …).
   This module only sets the carousel mechanics: fixed card WIDTH, equal heights
   via the stretching flex row, viewport clipping, and the controls bar.
   Tune width per instance via --ce-card-w on .ce-carousel.
