   DigitalSolomon v2 — design system (standalone / Cloud Run edition)

   Ported from the ratified v1 GHL design system, un-scoped for standalone
   hosting: v1 was wrapped in #ds-page with all:initial because it was pasted
   into a hostile GHL host page. Here we own the document, so tokens live on
   :root and we ship a normal reset.

   Tokens are the ratified solomon-brand v2 set. Do not add a colour that is
   not in that file. Accents cycle Gold -> Judgment Blue -> Cedar and map to the
   three products: DataSphere=Gold, SyncSphere=Blue, IntelAgent=Cedar.

   Contrast discipline (WCAG 2.2 AA): small accent text is chosen by BAND, not
   by product — Gold on Ink, Blue on light — because Gold/Cedar fail AA as small
   text on parchment and Blue fails on ink. Product identity shows through larger
   graphical elements (rules, icon chips, tags, headings) where 3:1 suffices.
