```

- **Fullscreen.** The game starts fullscreen without changing the saved settings.
- **Booth QR code.** A scannable, branded CodeRabbit link stays in the top-right corner on every route in booth mode. The provided code points to `https://coderabbit.link/ato26-ad?qr=1`, which identifies QR scans for attribution. To change the destination, regenerate `hoppys-adventure-arcade/Assets/booth/booth_qr.png` from the repository root with `swift hoppys-adventure-arcade/tools/booth/generate_qr.swift` and pass the output path and URL as optional arguments, then rebuild the game.
- **Idle reset.** After 90 seconds with no keyboard, mouse, touch or controller input, any game returns to the attract route. That is the hub, whose rotating previews act as the attract screen, unless `--attract=` names `beatem_up` or `runner`, the other menus that start their own music.
- **Game over.** A lost game doesn't offer unlimited retries. A player gets `--retries=<n>` retries (default 0); after that, the game shows no retry screen. Instead a **GAME OVER** card thanks the player, shows their score and counts down six seconds, then the attract route opens for the next player. The count starts again whenever the attract route opens. Every game takes part: Heroes vs. Villains, Code City Brawl, the platformer levels and the Endless Runner. Without `--booth`, every game keeps its own retry screen.
- **No quitting from the menu.** The menu's **Quit Game** does nothing in booth mode; staff close the window (Cmd+Q, Alt+F4).

🌐 Web query:

Apple Core Image CIFilter qrCodeGenerator output image extent quiet zone border documentation

💡 Result:

Apple’s documentation **doesn’t specify a quiet-zone or border size** for `CIQRCodeGenerator`. It documents the message and correction-level inputs, and says the filter generates a QR-code image with each module one point wide and high. ([developer.apple.com](https://developer.apple.com/library/archive/documentation/GraphicsImaging/Reference/CoreImageFilterReference/?utm_source=openai))

To determine the actual image dimensions, inspect `outputImage.extent` for the generated image; Apple documents `outputImage` as the filter’s `CIImage` result. ([developer.apple.com](https://developer.apple.com/documentation/coreimage/cifilter-swift.class/outputimage?changes=_3_10&utm_source=openai)) The docs don’t establish how much of that extent, if any, is quiet zone. If you need a specific border, add it yourself.

Add a four-module quiet zone before regenerating the QR asset.

The helper can regenerate a QR image with only a one-module border. The displayed asset adds only about three modules between the QR symbol and the adjacent labels. This does not preserve the required four-module quiet zone and can reduce scanning reliability in booth mode.

Update the QR image composition around qr.draw(in:) to preserve the QR symbol’s
original dimensions and center it within a white canvas with a four-module quiet
zone on every side; then regenerate the booth QR asset.
