/* GlitchCraft Engine effect: noise-overlay
   A very faint fractal-noise grain over the whole viewport — an inline SVG
   turbulence filter as a data URI, no external asset, no color dependency
   (it's just grayscale grain at low opacity, so it works unchanged on any
   theme). Extracted from glitchcraft.studio's .noise div/rule.

   Pseudo-element slot: html::after — see star-field.css for why ambient
   full-viewport effects each need their own reserved slot. */
