/* Episode viewer — section 12, "Watch one run, second by second".
   Owned by the viewer build. Pairs with js/viewer.js and the markup generated
   by build/make_viewer_partial.py.

   ── Page variables this file reads ─────────────────────────────────────────
   Every one is read as var(--name, <fallback>), so the viewer inherits the
   page's palette and type from site.css and still stands on its own if this
   file is opened alone. The names and the values below are site.css's:

     --ink       --muted    --ink-3    --bg      --surface
     --rule      --accent   --fail     --radius
     --measure   --font-sans           --font-mono

   The section heading and lede in the partial use the page's own
   .agp-section-head / .agp-h2 / .agp-lede classes, because build_site.py
   emits <section id="viewer"> empty.

   ── Variables this file owns ───────────────────────────────────────────────
   --ev-* only, all declared on .ev, so nothing leaks into the page. The lane
   hues are the dataviz reference palette's categorical slots 1, 2, 3, 4, 7, 5
   and its reserved status colour for a failed motion; identity is carried by
   the lane label and the legend as well as by hue.                         */
