steamFrame.dashboard.passthroughToggle: the SteamVR dashboard's room view button cycles Off -> colour (Arcturus Vision camera) -> monochrome IR -> Off, with a purple eye in colour mode. A Steam UI patch on the dock bar windows, a CDP relay and a small Rust helper that switches the camera source through SteamVR's IVRCameraPassthroughInternal_001 (vrclient.so from the SteamVR install, nothing vendored). Cleanup artifact for SteamVR's client log. Adapted from toorux/steam-frame-passthrough-toggle and KominoVR/frame-passthrough-shortcuts (MIT), see README Credits.
