The workflow canvas visual renderer (A2-P1 Packets 1–4) was built but unreachable by humans — now wired as its own top-level nav section (?section=canvas) as part of the navigation cleanup. A new CanvasTab lists the org's canvases, offers a "New canvas" action, and hands off to the existing WorkflowCanvasView for the selected canvas. Canvas is now reachable from the left rail, command palette, mobile pill nav, and a pre-connection preview card (#774, PR #775).
