   FIELDMARK — design tokens
   Palette: charcoal-navy ground, warm gold accent, muted pine
   secondary. Status colors read like a clipboard rating stamp,
   not a UI-kit default. Type: IBM Plex Sans (UI) + IBM Plex
   Mono (scores, readings, IDs) — instrumentation feel for a
   field-diagnostic tool.
