All of them
Toby moved a button two pixels because it looked cramped. It was a shared component, and Ines had already been round every screen it appears on.
The mistake
A two-pixel nudge with no blast radius attached to it. The component was shared, so the change was never to one screen — it was to every screen at once, and the only person who checked all of them was the one who found it.
