/* The shift is set in px by initTicker() in surge-animations.js, measured as the

   The old -50% only happened to be correct because the track's horizontal padding
   (14px + 14px) equalled the flex gap (28px) — change either and a -50% loop
   develops a seam. The measured value has no such dependency.
   -50% stays as the fallback for the (JS-disabled) case, where nothing animates
   anyway because .is-ready is never set. */
