Troubleshooting
No sound?
Click page first (autoplay restriction)
Check tab is actually hidden
Verify volume > 0
Check console for errors
Sound plays when tab active?
Enable debug mode
Check for "Tab is visible, skipping" message
Report as bug if missing
Mobile not working?
iOS requires user gesture per play
Consider visual fallback (flashing favicon)
