Show HN: One Thing at a Time Please – A Kanban board with one ticket slot (onethingatatimeplease.com)

I built a kanban board that only lets you have one ticket. That's the whole app. It's for PO's that get a little too excited sometimes.

This is a novelty project, built mostly with AI in a couple of hours. The AI wrote the code and the jokes—I just steered and said "no" a lot.

Don't put anything sensitive in there.
