class PlantFactory:
	"""Builds the heater/pot/sensor trio together as one consistent rig.

	Each component's type comes from its own config section (Heater.type,
	TempSensor.type) rather than a single plant_name key. The heater type
	determines sim vs real: sim gets Pot (modelled plant) and TempSensorSim;
	anything else gets PotReal and whatever TempSensor.type names.

	Delegates to HeaterFactory/TempSensorFactory so hardware-only deps
	(spidev, pyserial) stay lazily imported."""
