Open MBOX on Phone

MBOX files store one or more email messages in a mailbox export file.

• Phone file apps often show this format as raw text or cannot preview it clearly.
• The useful value is the readable article content, not just file metadata.
• A local browser preview avoids uploading private notes, notebooks, or documents.

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.
