Utility Bill Line-Item Decoder & Hidden Fee Detector (CSR/CFL/MHC/HFA Riders, Peak Demand, kWh↔Btu↔therm↔ton-hours)

Decode home and commercial electric/gas/water bills: classify tariff riders and charges (CSR/CFL/MHC/HFA-style codes, TOU on/off-peak, demand, capacity tag, decoupling), convert kWh↔Btu↔therms↔Ccf↔m³↔ton-hours with EIA factors, expose hidden fixed fees, and project annual cost with load-factor and peak-shaving savings.
