- Add aria-label to help overlay close button, drift ending START OVER button, offline popup Continue button
- Fix exportSave() URL.revokeObjectURL race condition (delay 1s before revoke)
- Remove duplicate exportSave/importSave definitions in utils.js (render.js has canonical file-based versions)
- All buttons now have aria-labels for screen reader accessibility

Closes #49
