   Superset Files — supersetfiles.com
   Site layer: materials, components, layout.

   Everything here derives from the product tokens in tokens.css.
   House rules, inherited from the product:
   - No glow. Depth comes from borders, inset highlights, bevels,
     and cast shadows only.
   - Glass is for chrome. Matte is for reading. Gel is for the one
     primary action on a screen. Jewel is for the icon.
   - Serif for reading, system sans for chrome, mono for metadata.
   - Motion is short, functional feedback — never ambient.
