 6. Delete the downloaded JSON file once the dashboard confirms that the session is authenticated.
 
 The extension observes only requests to Reddit's Matrix homeservers, verifies the captured token with Matrix `whoami`, reads Reddit cookies, and saves the combined export locally. It does not send the dump to any server; you upload it directly to your RedditBot dashboard.

+Before downloading, the extension independently resolves the current Reddit cookie identity and refuses the export unless its `t2` account ID matches Matrix `whoami`. Changing Reddit accounts clears the stored Matrix capture, so Reddit Chat must be reopened after every account switch.
