The animation begins with a dark red, subtly pulsing 3D heart and a 'Measuring...' status. Once the heart rate is detected, the heart instantly brightens to a vibrant red, and the text transitions to 'Current' with the live BPM. The heart then pulses dynamically in sync with the simulated heart rate, casting off concentric, glowing red wave rings that expand outward and fade into the dark background, providing a clear, tactile sense of a live pulse.
