Stopwatch
Start, pause, lap, reset. The clock keeps a millisecond display, splits on every Lap, and exports to a clipboard-ready table when you're done. State lives only in this tab.

How to use this stopwatch
- Click Start (or press Space) to begin timing. The clock advances from 00:00.000 with millisecond precision.
- Press Lap (or L) to record a split. Each lap shows its absolute split time and the per-lap delta.
- Press Pause (or Space again) to hold the clock; Resume continues from the paused value.
- Reset (or R) clears the elapsed time and all laps.
- When you're done, Copy as TSV sends the lap table to the clipboard, or Download .tsv saves it.
- Switching tabs pauses the display (the browser stops calling the renderer); switching back resumes from the correct value.
- Nothing is uploaded. The whole stopwatch runs in this tab.
