Feeds real temp_ist/temp_soll readings from a run log back into a fresh TempController (Normal mode) tick by tick, then plots a 3-panel comparison of heat rate and normalized power against the original logged values. Any PID gain can be overridden via --<section>-<gain> flags so candidate params can be evaluated against a past run without touching hardware.
