/* Signal For All V48.13 — strat decorativ de efecte continue (unde, forme plutitoare, 3D auto).
   TOT se oprește prin: prefers-reduced-motion, body.sfa-motion-off, body.sfa-calm, body.sfa-fx-off.
   Stratul este pur decorativ: aria-hidden, pointer-events:none, în spatele conținutului.
   FIX V48.13: eliminat CSS-ul pentru butonul propriu .sfa-zeromotion — butonul nu era
   niciodată adăugat în pagină de sfa-fx-v48.js (cod mort); controlul real de Zero Motion
   e panoul de accesibilitate (accessibility-v21.js), care rămâne singura sursă de adevăr. */
