An Omarchy shell plugin: a Python/asyncio daemon that discovers network displays and serves an encoded screen capture for them to pull, plus a Quickshell bar widget and panel to drive it. The screen comes from the xdg-desktop-portal ScreenCast interface (asked for every time, never remembered), goes through GStreamer, and is served from a local HTTP port. Desktop audio is mixed in from the default output's monitor. The container follows the receiver: WebM/VP8 for Cast, MPEG-TS/H.264 for DLNA, HLS for AirPlay video. The stream port has to be reachable from the LAN, and none of these protocols can carry a credential, so the capability is the URL: a fresh random path per session, refused to anything off the LAN, capped at four concurrent readers.
