            Linux bridge + tray app for the LCD panel of GAMEMAX IceBurg Digital AIO
            coolers. Built automatically from `${{ github.sha }}`.

            **Download** `GAMEMAX-LCD-x86_64.AppImage`, then:

            ```bash
            chmod +x GAMEMAX-LCD-x86_64.AppImage
            ./GAMEMAX-LCD-x86_64.AppImage            # tray + window
            ./GAMEMAX-LCD-x86_64.AppImage --selftest # verify the bundle starts
            ```

            Device access still needs the udev rule once:
            `sudo cp packaging/70-gamemax.rules /etc/udev/rules.d/ && sudo udevadm control --reload`

            **Integrity:** verify the download with the published SHA-256, or use
            `appimageupdatetool`/AppImageUpdate with the `.zsync` asset for delta updates.
            The built-in updater (v1.2.3+) also verifies that checksum before replacing itself.
