Quick AI Glasses Frame Trim

I need a small yet precise tweak to an Adobe Illustrator file of a pair of glasses. Your task is to remove only the left side of the frame following a custom-shaped path that I will supply the moment we start. Nothing else in the document should move, shift, or lose its layer structure—just that clean custom cut on the frame.

This is genuinely a 10-minute job for an experienced Illustrator user: open the file, apply the custom clipping path (or knife/pathfinder if you prefer), save, and return the updated .ai along with a high-resolution transparent PNG so I can see the result at a glance.

Acceptance criteria
• Left frame section is removed exactly along the provided custom shape
• All other artwork, artboards, and layer names remain untouched
• Final deliverables: updated .ai + transparent PNG preview

If you’re online and can turn this around immediately, let’s wrap it up now.
