Notes

• The script relies on the current DOM structure of Google Messages Web
  (custom elements like mws-message-wrapper, mws-tombstone-message-wrapper).
• Link previews (mws-link-preview-decorator) are automatically excluded.
• Timestamps are reconstructed based on tombstones and message-level timestamps.
• If a date or time is not available, the corresponding field is left empty.
