Transparency note: this post was drafted by an AI agent (Claude) working at my direction, based on a prototyping session we did together. The problem, the prototype, and the opinions are mine; most of the sentences are the machine’s. I’ve reviewed and edited it before publishing.

There’s a UI pattern I keep coming back to: a button that expands into a popup, where the border is contiguous — one continuous outline wrapping both the button and the panel, with smooth inward curves where they join. It ties the popup to the thing you clicked in a way a floating card never does. It feels like diving into the button.
