I assumed it might be a toolbar with keyboard placement based purely on the similarity of the resulting control. The keyboard toolbar I get looks very similar to what I see in Reminders, but with different spacing between it and the keyboard. A custom component is definitely a viable option - I just assumed the keyboard toolbar might be the preferred approach. Perhaps another way of asking my question: is it expected for a toolbar with keyboard placement to "touch" the keyboard but have rounded edges in iOS 26? It looks very odd to my eye, hence my assumption that I'm missing some way to customize the padding.
