/* Axon Studio — studio-canvas (docs/studio.md §11). Owner: see docs/studio.md; prefix st- (studio), stc- (canvas), sts- (sources), sta- (agent).
   The node-graph editor (js/studio/editor/*). Type leads the hierarchy, surfaces separate layers, colour carries
   meaning only: a node's category tints its title bar, a port's type colours its socket and its wires, and status
   colours appear only where a run says something. Row heights mirror js/studio/editor/geometry.js (HEAD 36, ROW 24,
   PARAM 30, PREVIEW 76, FOOT 28): sockets are placed by computation, so keep both in step. */
