The console grew a "Streamed screen" card and the host grew a
PUNKTFUNK_CAPTURE_MONITOR knob and a list-monitors command, and the docs
knew about none of it — a control with no explanation anywhere.
virtual-displays.md gets the feature section: what it is for, that the
monitor is never touched, that its resolution wins and a client scales,
that a bad name is a hard error rather than a different screen, and that
there is no chooser dialog on any of the four backends (which is what
makes it work unattended). Plus the three troubleshooting entries the
shape of the feature predicts: settings that do nothing while mirroring,
a console card the env var has locked, and a pin that names no head.
host-cli.md documents list-monitors and mirror-test; configuration.md
gets the knob, including that it outranks the console on purpose;
running-as-a-service.md gets the desktop-session drop-in and states that
the host needs nothing exported to find its session.
