/* Ambient background: a handful of very soft, very slow-drifting glow

   as a decoration you consciously notice. This is the site-wide answer to
   "always something being watched and evaluated": nothing here ever
   fully stops moving, but on any given screenful you'd struggle to catch
   it mid-motion. Pure background-position animation (no extra markup),
   so it's on every page this stylesheet reaches. Sections with their own
   opaque background (cards, .alt-bg, the CTA band) simply sit on top of
   it, giving the page a sense of surface panels floating over open water.
