The runner's Machine subclass fetches lid/head images from the forgectrl snapshot endpoint - forgectrl owns the imx-media pipeline whenever a stream client (LightBurn) is connected, so direct V4L2 grabs fail busy. Head captures request lamp=0 (the cloud's focus analysis needs torch-off images); the HCil measure-laser LED is still driven directly. Direct capture remains the fallback when the daemon is unreachable. The sample config gains the factory-board settings: the estop motion gate stays off (the board's estop sense reads low during any motion), and the forgectrl URL is configurable.
