When I archive a card in Deck, all assigned users are removed from the card. This is unexpected for my workflow, because I would like to keep track of who was responsible for a card, even after it is archived. Currently, there doesn’t seem to be a setting to control this behavior.

Describe the solution you'd like
I would like an option (either default or configurable) that allows assigned users to remain visible on cards after they are archived. This would help with accountability and tracking, especially when reviewing completed or archived tasks later.

Describe alternatives you've considered
I have checked the settings and documentation, but could not find a way to keep user assignments on archived cards. Manually noting assigned users before archiving is not practical.

Additional context
Tested on Deck version 1.15.1. The issue occurs for all users/cards, and is consistent across boards.
If this is intentional, please consider making it configurable, or clarify the reasoning in the documentation.

Thank you for considering this feature!

No files or tests are named. Start by tracing how Deck 1.15.1 archives cards and clears assignments, then determine whether retention should be default or configurable. Done means archived cards preserve visible assignees and the chosen behavior is covered by tests.
