Writing the slot picker in React as a designer
Why I wrote the component myself, what I got wrong, and what the engineers kept.

The slot picker had one animation that mattered: the selected time had to stay put while the day changed. Every handoff lost it.
Writing it
I wrote the first version in a branch, with the tokens we already had. It was slower than it should have been and the engineers rewrote the data layer.
What stayed
The motion, the keyboard handling and the empty states. Those were the parts a spec never captured.
