• Phone file apps usually cannot inspect Chrome extension packages.
• The useful metadata is hidden behind the CRX header and embedded manifest.
• A safe preview should avoid showing extension source code or implying a security audit.

OpenOnPhone is for quick local inspection. It does not replace the original professional app for editing, conversion, exact layout, formulas, measurements, security review, or full workflow features.
