/* Footer – "Flowing Data" background (CSS-only)
   -----------------------------------------------
   How the keyframes work:
   The background is a repeating pattern of thin horizontal lines. background-size
   defines one "tile" height (e.g. 32px). The animation moves background-position
   from 0 to that tile height (e.g. 0 → 32px on the Y axis). Because the pattern
   repeats every tile, when we shift by exactly one tile the scene looks identical,
   so the animation loops seamlessly. The lines appear to drift downward (or use
   negative values to drift up). Speed = animation duration: higher seconds =
   slower shimmer (e.g. 20s), lower = faster (e.g. 8s). Use --footer-data-duration.

   Variables you can change:
   --footer-data-duration   Animation length in seconds (e.g. 15s = slow).
   --footer-data-line-size  Vertical repeat size in px; also the keyframe distance.
   --footer-data-line-color Line color (default #333 on #0A0A0A).
