photonforge-live-viewer

The PhotonForge LiveViewer is a local, interactive 2D layout viewer for pf.Component and circuits: from photonforge.live_viewer import LiveViewer, point it at a component, and it serves a browser view that redraws as you edit the design - the primary visual feedback loop while building layouts. Covers the Python lifecycle (open on a fixed port, push updates, show several components together, fit large devices, release the port) and the browser-side window.lvApi that lets an AI agent drive the viewer headlessly: zoom/pan/fit the camera, toggle layers, inspect the shape at a point, measure distances, and read the layer list, cell hierarchy, and camera state. Use when the user wants to see or iterate on a PhotonForge layout, run a viewer script, drive or inspect the viewer programmatically, or fix a stuck/port-in-use LiveViewer.
