/* Optional. efx_pix.js applies these same rules inline, so the effect works even
   if this file is missing or served stale from a WP cache. Kept only as a styling
   hook.

   Two rules that must not be changed:
   - never give this canvas a negative z-index; it would paint behind the cover
     block's opaque background and vanish
   - keep pointer-events:none, or the overlay swallows every click on the page */
