Billfold Wallet Security
A sparse security screen for a wallet: face unlock, an unlock threshold answered with the reader's own spending (how many of the last thirty days of payments sit above it, counted from the activity array), a lock everything control, and three devices as plain rows with a last used figure worked out against the reference date and a working revoke.
Paste into Claude Code, Cursor or Windsurf. It builds this screen 1:1 in your app.

The rule this design follows
It ships exactly as previewed: same colors, same type, same copy, same motion. The prompt tells your agent to build that, and not to adapt it to your existing theme.
