/* Knight Rider / Cylon scanner — pure CSS, no JS.
   1. The text fill is replaced with a gradient (white → red blob → white)
      twice as wide as the element. background-position animates the blob
      across, and `animation-direction: alternate` bounces it back.
   2. ::before is the glowing scanner dot that rolls beneath the text.
   Both animations share the same timing so they stay locked together. */
