   IXLabsNL — orange.css
   THE ORANGE PRINT: glass, radius, depth. Loaded LAST on every page, after
   tokens-orange.css. No raw colour here — every value is a token.

   The night sheet had a rule: no radius, no shadow, depth is hairline. This
   print reverses it on purpose. On a warm white ground depth is a soft warm
   shadow and a frosted panel with a bright edge; corners are rounded because a
   pane of glass is.

     2. Chrome — bar, search, buttons, forms, footer
     3. The stage — map pins with photographs, the register, the room
     4. The sections of the home page
     5. Lab and text pages
