## Node Interaction Model

What happens when you interact with a processor node on the diagram?

### A: Click-Select + Right-Click Menu

Click to select a node (amber highlight ring). Right-click for context menu with tracing/tap/snapshot actions. Clean separation of concerns. Standard desktop UX.

### B: Hover Floating Toolbar

Hover reveals a dark floating icon toolbar above the node. Click still selects. More discoverable than right-click, but can feel cluttered on dense diagrams.
