The live connection reads tray_now (unit × 4 + slot, 254 external, 255
none) and works out the unit by id or, failing that, by position — so the
A2L's AMS lite numbered 16 is handled. Cards say 'Using' (or 'Loaded' when
not printing) with the filament's name and slot, mark the slot in the list,
and draw a tube in its colour from that spool to the toolhead, with a
moving flow while printing. The external spool is drawn when it's in use.
Debug reports include tray_now and tray_tar.

A printer mid-print reports every second, and each report restarted the
five-second wait, so a printing printer's spools never synced. Only a change
in what's loaded restarts it now. Printers without a chamber sensor report
5 °C, which is no longer shown.

Each printer now has one MQTT connection that stays open, merging the
partial reports printers send while printing. Cards poll every 3 seconds
(paused while the tab is hidden) and show state, file, progress with time
left and finish time, layer, nozzle/bed/chamber temperatures, speed
setting, and print error and HMS codes. A spool change syncs the Filament
page and the card's drawing within seconds; a full report is requested
every 10 minutes as a backstop, replacing the 10-minute probe loop.
"Test & sync" uses the open connection rather than making a second one
(?debug=1 still makes a short separate one). Connections are reconciled
when printers are added, edited or removed.
