   GMAIL CHECKER — LIQUID GLASS
   A cinematic near-black room with a few large panes of glass floating
   in it. Everything expensive (backdrop-filter, blend modes, animated
   blur) lives behind `html:not(.lite)` — Safari and phones get solid
   gradient equivalents that look the same and cost nothing.

   Material classes
     .lg    big tinted glass pane        (a handful per screen, no more)
     .lg-r  refractive pane              (Chromium gets the SVG displacement)
     .sheen pointer-lit specular highlight
     .pane  cheap inner surface          (NO backdrop-filter — never stack)
