Build an audio-product hero with Tailwind CSS: headline and copy on the left, and on the right a recorder demo with a waveform canvas, a large record button that toggles a pulsing animation and a live-drawn waveform, and a playback scrubber. Keep the whole demo CSS and canvas driven — no audio files needed — and label it clearly as a demo so users know it is not recording them.
