/* "Flash" attention effect on the whole board, per request. The board's
   own fill stays solid brand purple at all times (never changes color) --
   what pulses is a soft gold (the logo's own accent color) glow, so the
   box always satisfies "background = KK's color" while still visibly
   flashing. Strengthened per feedback that the original single, tight
   6px ring was too subtle to read as a "flash": now a bright inner ring
   plus a wider, softer outer bloom, with a very slight scale pop (a
   transform, so it never shifts surrounding layout). Kept at a 1.6s cycle
   (~0.6 flashes/second) -- clearly readable as pulsing while staying well
   under the ~3-flashes/second photosensitive-seizure threshold -- and
   switched off for anyone with prefers-reduced-motion set.
   Performance note (2026-09-26): the glow used to be produced by animating
   box-shadow directly, which PageSpeed flagged as a "non-composited
   animation" (box-shadow repaints on every frame). The same gold glow now
   lives, fully drawn, on an ::after layer and only its opacity is
   animated; the scale pop stays a transform. Opacity and transform are
   both compositor-only, so the look is unchanged but the browser no
   longer repaints the board on each frame. .ad-slot--rail (defined
   further down) overrides position: relative with position: absolute,
   which still anchors the ::after layer correctly. */
