Reads real-time heart rate from MR60BHA2 60 GHz mmWave sensor and
estimates BP trends using HR/HRV correlation model:
- Mean HR → baseline SBP/DBP
- SDNN (HRV) → sympathetic/parasympathetic adjustment
- LF/HF spectral ratio → fine adjustment (with numpy)
- Optional calibration with a real BP reading
Verified on real hardware: 125/83 mmHg estimate from 35 HR samples
over 60 seconds at 84 bpm mean HR with 91ms SDNN.
