"Picks whether a targeted client adapts its own screen share after it starts. A targeted \
client measures what the encoder sends, steps the share down a resolution and frame rate \
ladder while it cannot keep up, probes back up when it can, remembers the settled rung \
per codec, and tells the sharer what is going out. A client that is not targeted \
publishes the same target and never changes it. Both arms still get the publish-time \
fixes and both arms still recover a stalled encoder. While the master switch below is \
off every client publishes and holds, whatever the rest of these fields say.",
