Open roff on Phone

roff files store text formatting source used by Unix manual pages and technical documents.

• 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.
