        help
            When set to a valid MAC address (e.g. "AA:BB:CC:DD:EE:FF"),
            only CSI frames from that transmitter are processed. All
            other frames are silently dropped. This prevents signal
            mixing in multi-AP environments.

            Leave empty to accept CSI from all transmitters.

            Can be overridden at runtime via NVS key "filter_mac"
            (6-byte blob) without reflashing.

            Controls the level of on-device CSI processing:

            0 = Disabled. Raw CSI frames are streamed unchanged (default).
                This preserves full backward compatibility.

            1 = Phase sanitization + Welford statistics + top-K subcarrier
                selection + delta compression. Runs on Core 1.

                extraction (breathing/heart rate), motion scoring,
                and fall detection. Sends vitals packets over UDP.

            3 = Reserved for future ML inference tier.

            Amplitude variance threshold for presence detection.
            Higher = less sensitive. Values below threshold/2 indicate
            empty room; values above threshold indicate motion.

            Minimum variance spike (scaled by 100) required for fall
            detection. The actual threshold is also gated by 5-sigma

            Number of phase history samples used for vital signs
            estimation. At 20 Hz CSI rate, 300 frames = 15 seconds.

            Number of highest-variance subcarriers to select for
            downstream processing (vital signs, delta compression).
            32 is a good default for HT20 (64 subcarriers).
            Increase for HT40 (128 subcarriers).
