/* ── Aether case study: the media that sits between the sections ─────────────
   Six small pictures of the product and the problem, drawn in HTML rather than
   recorded, in the same Obsidian-dark surface the hero film uses. The markup
   in the page is each picture's finished state; assets/js/aether-media.js arms
   them and plays the pieces in when a picture scrolls into view. Without the
   script, or with reduced motion, they simply sit finished.

   They stay dark in both themes: they are pictures of a dark app. */
