/* ==========================================================================
   Telamorph — Media carousel
   A lightweight crossfade carousel for background-image media tiles. Slides
   stack absolutely and the active one fades in; carousel.js auto-advances
   (paused on hover, focus and when offscreen) and injects clickable dots.
   Progressive enhancement: with no JS the first slide stays visible and no
   dots are added. Reduced motion: no autoplay and instant slide swaps.

   mirroring the composite scrolly's settle so the swap reads as an intentional
   move rather than a flat dissolve over a resizing frame. */

   Each dot's clickable area is bigger than its visual mark: the button is
