/**
 * Game Platform SDK
 *
 * When running inside the platform, window.GameSDK is injected automatically
 * before your bundle loads. Use it directly:
 *
 *   const result = await GameSDK.submit(score)
 *   // result: { ok: true, rank: 3 } or { ok: false, error: '...' }
 *
 *   const name = GameSDK.getPlayerName()  // the current player's display name
 *   const id   = GameSDK.gameId           // this game's id string
 *
 * For local development (outside the platform), load this file as a script
 * tag before your bundle and call GameSDK.init(gameId, apiBase):
 *
 *   <script src="game-sdk.js"></script>
 *   <script>GameSDK.init('my-game', 'http://localhost:4006')</script>
 *   <script src="my-game.bundle.js"></script>
