# Manual: full mirrored upstream A/V sync probe.
#
# This probe intentionally uses the normal lesavka-client capture path as the
# sender. A local browser stimulus is captured by the real webcam and real mic,
# Lesavka relays those live captures to Theia, and a Tethys browser records the
# Lesavka UVC/UAC devices via getUserMedia before analysis.
