/**
 * The `<MaterialGameSounds/>` {@link GameProvider} mounts on every game's behalf, so the sounds the framework
 * gives materials by default are heard without each game having to remember to mount the component. Half the
 * games never did, and a default nobody hears is not a default.
 *
 * It stands down as soon as a game mounts its own — see {@link registerExplicitSounds} for why two instances
 * cannot coexist. That is what lets the games already mounting it, some with an `ambiance` or an
 * `onSoundsLoad` of their own, keep working untouched: their instance wins, this one goes quiet, and their
 * `App.tsx` can be cleaned up later or never.
