The code for the gitban card with id px9k89 has been approved as of commit 39919f4. Please use the gitban tools to update the gitban card and begin the tasks required to properly complete it.

## Card Close-out tasks:
- Use gitban's checkbox tools to ensure all checkboxes on the card are checked off for completed work if not already.
- Do not mark any work as deferred. This card will be closed and archived and likely never seen again.
- Use gitban's complete card tool to submit and validate if not already completed.
- Close-out items: Check off the "Code Review Approved" checkbox in the Completion Checklist. The Documentation checkbox is intentionally left unchecked (scoped to a separate step-5 card). The remaining Completion Checklist items (deployed, monitoring, stakeholders, follow-up, epic closed) should be checked as appropriate during close-out.
- If this card is not in a sprint, push the feature branch and create a draft PR to main using `gh pr create --draft`. Do not merge it -- the user reviews and merges.

Note: You are closing out this card only. The dispatcher owns sprint lifecycle -- do not close, archive, or finalize the sprint itself. The exception is a sprint close-out card, which will be obvious from its content.
