iOS overlay — deck-swap test

1. Tap Start, then Pop PiP.
2. The floating window shows OPPONENT or MY DECK in big text + a live counter.
3. Tap the PiP pause button → it should flip OPPONENT ↔ MY DECK and keep counting (NOT freeze, NOT flip on its own).
4. Optional: tap Watchdog: OFF to turn it ON and see if the live counter freezes (that was the data-killer).
5. Screenshot the log when done.
