/* Constraint Check Desk: shared styles. No build step.
   Visual system: the TNFA Design System (https://claude.ai/artifact/FGtwDL393QuVYodATMiRLR).

   The dark theme is a tool-only extension derived from the same tokens; the website has none.
   --chart-* and --tier-* are the TNFA data palette (validated for colour-vision deficiency and contrast). */
