/* ===========================================
   DIAGNOXAL - Disorder graph (mind map) styles
   Owner: PBI-013. Consumed by ui/js/graph-view.js.

   Motion values are consumed from the canonical site motion tokens
   (--motion-fast / --motion-base / --ease-out / --ease-inout). This file
   defines no tokens or literal motion fallbacks of its own.

   Colour rule: amber (--color-warning #D69E2E) appears here only as the
   rule-out relationship encoding, which is drawn by graph-view.js from
   ConceptMap.EDGE_TYPES. No amber is used for state, achievement or chrome.
