Porting a game to YouTube Playables

Every game ships as a web build — an index.html at the root that loads the YouTube Playables SDK before any game code, which creates the sandboxed YouTube runtime:

<script src="https://www.youtube.com/game_api/v1"></script>

Requirements verified at publish time:

• The Playables SDK is loaded before any other script.
• ytgame.game.firstFrameReady() is called before ytgame.game.gameReady(), and gameReady() fires within ~5 seconds.
• Initial bundle stays under 30 MiB; cloud‑save payload under 3 MiB.
• Platform hooks are wired up: audio/mute (onAudioEnabledChange), pause & resume, scores (sendScore, integer), cloud saves (loadData/saveData), and language/i18n.
• Design rules are met: fixed aspect ratio & orientation, no external links, no in‑game sharing.
