   Diagnose.Codes — brand design tokens & site chrome
   Derived from the existing diagnose.codes marketing site: heavy condensed
   display type, near-black/navy backgrounds, electric blue accent, sharp
   (non-rounded) UI chrome. The VRM product UI intentionally breaks from
   sharp corners — see app.css — everything in this file stays true to the
   marketing brand.
