Notes
- Times are written as floating local time or as UTC; floating times show at the same wall-clock hour in every timezone, UTC times shift with the viewer.
- Line folding, escaping and required fields (UID, DTSTAMP) follow RFC 5545, so strict parsers accept the output.
- Runs 100% in your browser — your files and data never leave your device.
