## Configuration for all controllable devices in the simulation

Every device collection is a ``dict[str, <Settings>]`` keyed by
``device_id``.  This makes config paths stable regardless of
declaration order and lets each device settings class build its own
config path from ``self.device_id`` without needing an external index.
