/* NucLex-owl (NucLex ontology workbench on Snow Owl), styled to NUCLEX-BRAND-001 v2.0 (brand/tokens.json).
   Light only, no pink. NucLex Blue for the mark, headings and outline buttons; NucLex Red is editorial
   (the rule above page titles) and never an error; Orange once per view as a fill (the primary action);
   Concept Blue for anything you can follow in the ontology. Source Serif 4, Arimo, IBM Plex Mono,
   self-hosted from brand/fonts. Cards: White, Hairline, 12px radius, card shadow.
   Layout: white masthead with a hairline, then list pane + document pane + rail; footer on Page Gray. */
