Three bits of polish for people who did not write this. The payload serves /manifest.webmanifest and /icon-192.png, and the page points at both, so a phone can keep the controller on its home screen instead of typing an IP address again. The icon is the app's own icon, rendered by the launcher's drawing code and committed, so the payload build needs no renderer; a test re-renders it and fails if the two drift apart. One size only: the gradient does not compress, and a 512 copy would add 150 KB for a splash screen that a plain HTTP shortcut never shows. write_png now picks the best filter per row, which also shrinks the package icon. When the service starts it works out which address the console is actually reachable on, from the route to the outside world without sending anything, and puts it in the start-up notification on the TV. Every error the page can show now says what happened and what to do about it, rather than "Invalid axis", and the README has a troubleshooting section covering the ones people will actually hit.
