Copper Key Circuit

Recovered chips charge two transfer pads. Pulse across the partition while retaining the data, but still collect the copper key to open the exit-side door.

Collect both data chips and a key, unlock the door, and reach E. Avoid the marked hazard.

Tap or click the controls. Keyboard: Tab and Enter/Space operate every button; arrows/WASD move where available, R restarts, Z undoes calm puzzles.

This challenge has reachable failure. Restart returns to the same fair opening.
