activity-diagram

Consistent UML activity diagrams — flowcharts with UML semantics: parallelism (fork/join), guards, and swimlanes.

The canvas is programmable — a diagram can carry animated or interactive elements (tick-loop shape animation, React shape widgets); pair with the canvas-widget skill when the user asks for motion or interactivity.

• Read ./reference.md — node vocabulary, swimlane math, layout.
