This organ OWNS the emit: it reads the source, applies the camera-mirror fix IN the emit, 6// and writes the deployable client to knowledge/staging/video/. Edit the organ -> emit -> deploy (vault 7// organs) -> verify LIVE via nx_live_verify (find THIS marker in the served bytes). No more hand-editing 8// the deployed JS; the organ is the SSOT of the transform. 9// 10// RUNG 0 fix = SELF-VIEW MIRROR (the reported camera-flip): mark the self tile (class "tile self") + a 11// CSS rule mirrors ONLY the self <video> (selfie feel); the SENT frame stays un-mirrored (remote correct). 12// RUNG 1 (next) = TX flip-toggle + inter-frame coding into the emit.
