docs(tasks): the orbit faders are fine — it is the Master that sits 30 dB down

check-mix against the running session: twelve orbit faders between +0.0 and +6.0 dB,
none muted, all routed to master. The overnight -inf reading does not hold. Master
-30.2 dB is the real finding, and with OSC off only PLN's eyes can confirm the live value.
