[HealthKit] We read HRV, heart rate, resting HR, sleep, steps, workouts, environmental audio, SpO₂, respiratory rate, body temperature, body fat %, VO₂ max, and time in daylight (iOS 17+) to show stress status, sleep insights, and an estimated “body age.” We write dietary water and caffeine when the user logs habits.
