   MATERIAL — glass is a material with depth levels, not a layout.
   .glass            elevated surface (default)
   .glass--thin      floating chips, small overlays
   .glass--strong    interactive / modal surfaces (form, ID card, featured plan)
   .glass--dark      glass on dark scenes
   .inset            recessed surface (no blur)
   .glass--still     same material without live blur. Rule: blur only where real
                     content passes behind (nav, menu, dock, hero chips, photo tag).
                     Over smooth light fields blur is invisible and only costs GPU.
   Each layer: translucent fill → backdrop blur/saturation → edge reflection
   (::before, gradient hairline) → specular sheen + grain (::after) → shadow.
