## Mandel additional usability improvements — October 24, 2026

Reviewed live Chicken Coop and Ventilation pages plus coop register catalog. Existing heating/cooling/daily fan target/light controls and ventilation speed/pressure settings already present; retained. Added to page_alarms a Live Pressure Overview near top: four read-only psi cards for g_tankPres_out_eu, g_wellPres_out_eu, g_filterDeltaPres_out_eu, g_airPressure_out_eu. Added neutral explanation that badges are controller alarm outputs and latched alarms may stay active inside limits (general behavior, not a diagnosis).

Added Air Compressor Pressure section matching the three water sections: eight threshold/reset-gap numeric controls, eight limit/alarm enable switches, three fault enable switches, seven grayNormal/redActive/NoData state badges. Uses g_airPressure_limits_{lo,lolo,hi,hihi}_{in_sp,in_hyst,in_en,alm_in_en,alm_out} and g_airPressure_faults_{chan,under,over}_{in_en,out}. Enabled13 existing polling definitions (LL/HH hyst; eight limit/alarm enables; three fault enables), ON_CHANGE1sec preserved. No live PLC setting values, enables, modes, run commands, resets or acknowledgement writes.

Earlier six active water outputs have cleared externally/by controller; no reset performed by this task and cause not established. Existing roots preserved; new roots added.
