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.
