   GLASS PANELS
   backdrop-filter blur + saturate, inset highlights for the
   thickness of the pane, a slow specular sweep, and grain.

   NOT refraction. `backdrop-filter: url(#svgFilter)` is a no-op
   in Chrome — CSS.supports() reports true but no filter primitive
   is ever applied, verified at displacement scale 400 against an
   unfiltered reference (byte-identical). Real refraction of live
   DOM is not achievable this way; the WebGL glass in the Play
   section refracts a texture instead, which does work.
