What it does

Written by AI from the README

Saves page snapshots for selected items that have a URL but no snapshot. A second command makes a clean reader-view copy of a snapshot as its own attachment.

Saving several items at once from the Zotero Connector skips snapshots, so these items end up with only a link. This backfills them afterwards and offers a clutter-free copy for reading.
