Find your frequency

Create a self-contained SVG motion graphic in a single HTML file.

ART DIRECTION
Use dusty pink (#f0c9d9) and mulberry (#792d56). Arrange 36 narrow rounded vertical bars across the middle. Modulate their heights with a traveling sine wave; all bars share the same vertical center. Add FIND YOUR FREQUENCY at the top and A STUDY IN RHYTHM at the bottom. This is a visual rhythm study, not an audio-reactive visualization.

TECHNICAL RULES
- Use a 960 × 600 viewBox (8:5). Scale responsively without cropping.
- The loop lasts exactly 6 seconds. Use deterministic, time-based drawing with requestAnimationFrame; do not accumulate frame deltas.
- Keep all shapes and text inside the safe area. Use system sans-serif fonts and no external assets, libraries, or network requests.
- Use a static representative frame when prefers-reduced-motion is enabled, and include a visible play/pause control.
- Pause when the document is hidden.
- Return the complete HTML, CSS, and JavaScript, with no omitted sections.

DELIVERY
Make the text, colors, and example data easy to edit. Explain which values to change. The supplied reference is an original implementation, not proof that any model reproduces this prompt exactly.
