/* frontend/css/semantic-layers.css
   Semantic layers story view (Settings → Taxonomy landing) — WP03,
   mission semantic-layers-settings-01KXHYDW.

   Visual sibling of the sales-deck diagrams (diagram-7 / diagram-3a–c):
   three numbered colour-role cards (1·Lexical red / 2·Taxonomy blue /
   3·Ontology green), a domain pill switcher, a journey demonstrator and the
   "How it pans out" table. All colours derive from the app theme tokens
   (styles.css :root / [data-theme="dark"]) — the three accent roles map to
   --error-color / --primary-color / --success-color so both themes work
   without any theme-breaking hardcoded hexes. */
