/* ---- logo shine ----
   The mark is one PNG with a gold hexagon overlapping a silver one, so a
   single flat shine sweep can't be brighter on just the silver side. Two
   alpha-only crops of the same source (logo-icon-gold-mask.png /
   logo-icon-silver-mask.png — silver/gold pixels isolated by saturation,
   everything else transparent) are used as CSS masks so each half gets its
   own independently-timed highlight band. Silver's sweeps faster and lands
   brighter per the ask; gold gets a slower, dimmer pass so it doesn't
   compete. Kept as a slow periodic "glint" (a quick pass, then a long hold)
   rather than a continuous back-and-forth shimmer, which reads as gimmicky
   on a site that's supposed to feel trustworthy — and reduced-motion users
   get a still logo. */
