"""The live status push carries what the printer card reads from the status (PSF-3, PSF-4).

The websocket push replaces the fields it carries in the card's cached status.
``airduct_mode`` was missing, so switching cooling/heating on the printer's
screen showed the old mode until the next REST poll; ``nozzle_rack[]`` lacked
``filament_type``, and since the push replaces the whole rack an H2C slot
lost its material label on every push.
