/*
FNXC:WorkflowSimpleView 2026-07-10-12:00:
Simplified workflow view styling. Requirements encoded here:
 - A modern node-card look competitive with leading workflow builders: soft
   rounded cards, a colored icon chip per node family (agent / automation /
   flow control / merge), quiet default edges, and a clear selected ring.
 - All colors derive from the dashboard theme tokens so light/dark and color
   themes cascade without per-theme overrides.
 - Touch-first hit targets: the edge "+" insert button and the "Add step"
   pill are ≥32px so the same canvas serves the mobile graph view.
