admin b5a08bb393 Task 2: Build ECG flatline and first heartbeat ...

Add the ECG animation phase between boot sequence fade and CV reveal.
After boot text fades out, a green flatline draws left-to-right across
the viewport center over 1000ms, followed by a PQRST heartbeat waveform
(R peak 40px) animating over 600ms. Uses SVG with stroke-dasharray/
dashoffset for line-drawing effect with green glow filter. The
drawHeartbeat() function is reusable for Task 3's escalating beats.
