 -   **Process Isolation:** When a measurement is started, the frontend launches its corresponding backend logic in a separate, isolated process using Python's `multiprocessing` library. This is the key to PICA's stability: a crash or error in one measurement script will not affect the main launcher or any other running experiments.
