## Workflow playground

Building a workflow used to mean writing DOT by hand. The new `/playground` page lets you build one by describing it: chat with Ask Fabro on the right while a live canvas re-renders the workflow graph on the left. The canvas supports pan, zoom, fit-to-window, click-to-inspect node details, and a Play button that walks through the graph so you can sanity-check the flow before running anything.

When you're happy with it, download the workflow as a `.fabro.zip` — including `workflow.fabro`, `workflow.toml`, and a README — or use **Run for real** to create an actual run and jump straight to its run page.
