Thousands of golden lines—the traces—spiderwebbed between them, carrying phantom voltages.

The physical board showed no damage there, but the boardview revealed it was the last stop before the CPU. She opened the file on her triple-screen setup
This was a puzzle of electricity.
“Open,” she muttered. An inner-layer break. Capacitors, pale blue ovals
