One-time code boxes that fill from a paste or platform autofill and step back on Backspace. The active box shows a dark edge and a caret, invalid shows in the edges; an optional status folds the boxes into a centered, edgeless Verifying pill that turns to Verified, or opens back up on a wrong code.
