In boards used for collecting ideas, feature requests, or backlog items, it is currently difficult to understand which cards are most important to users. All cards have the same visual weight, and prioritization requires manual discussion or external tools. This becomes frustrating when many users want to express preferences / prioritization or support for specific ideas.

Describe the solution you'd like

Add a voting system to Deck cards that allows users to vote (e.g. upvote) on cards.
Each card should display its vote count, and the deck should support sorting or filtering cards by number of votes (for example: highest votes first, lowest first, etc.).

This would enable team-driven prioritization of ideas, similar to >> see Additional context

Using other tools

Additional context

This feature would be especially useful for:

Internal product or roadmap prioritization

Comparable implementations exist in tools like:
Salesforce Ideas,
Trello voting power-ups, (https://trello.com/power-ups/55a5d917446f517774210013)

The issue does not name any files, tests, or entry points. Start by tracing how Deck cards are stored and rendered, then identify the existing card ordering and filtering paths. Done should include user voting, visible vote counts, and sorting or filtering cards by vote count, with behavior covered by the relevant tests.
