Fixes macOS Chrome printing so the default three labels produce one page instead of a trailing blank page. Print output now includes only populated labels and excludes editor accessibility shortcuts, while preserving exact Avery-compatible positions and multi-page jobs.

Improved canvas navigation and printing:
- Scroll normally on the canvas; pinch or hold Command/Control while scrolling to zoom toward the pointer, now up to 300%.
- Sheet names now control exported filenames; the redundant project-name field was removed.
- Printing skips pages that contain no labels and uses stronger page-break handling.

Updated the store-facing name and summary for clearer address and shipping label discovery. Added a custom icon, four product screenshots, and the Labeloo homepage. Version 0.4.3 keeps the minimal permission model.
