   Loaded on every page, after site.css. Adds movement, tickers, animated
   figures and the social row, using the site's own tokens.

   Every animation here is opt-out: `prefers-reduced-motion: reduce` stops all
   of it, marquees pause on hover and on keyboard focus, and nothing that
   carries meaning depends on movement to be readable.

   11. Reduced motion — a gentle exception

   site.css kills every animation and transition when the visitor asks for
   reduced motion. That is a safe default, but stricter than the guidance
   requires: what reduce-motion exists to prevent is *movement* — sliding,
   parallax, spinning, zooming — because that is what triggers vestibular
   discomfort. A cross-fade has no movement in it.

   So under reduced motion we keep a short opacity fade and drop every
   transform. Nothing slides, nothing loops, nothing moves; content still
   arrives softly instead of snapping in.

   12. Image descriptions inside a photo caption
   --------------------------------------------------------------------------
   .g-cell figcaption is white text on a dark scrim over the photograph. The
   description line added beneath the label inherited --slate (#4E6480), which
   is dark blue-grey on near-black — effectively invisible. It also made the
   caption two lines tall, pushing text up into the part of the scrim that
   fades to transparent, so on a bright photograph even the white label became
   hard to read.

   Both are fixed here: a light colour for the description, and a scrim that
   stays opaque across the whole caption rather than only at its foot.
