/*
  wikipathways-submit — design system
  --------------------------------------------------
  Visual idea: the curation desk. WPIDs are treated like museum/herbarium
  accession numbers (a serif "ledger" numeral in a tagged chip with a
  grommet), pathway diffs are shown as two labelled frames joined by a
  single edge — the same node + edge grammar GPML itself uses. Palette is
  a desaturated sage/forest range (not the generic cream+terracotta or
  near-black+neon defaults), sans UI chrome, serif for accession numbers
  and headline emphasis only, monospace for identifiers/paths.
