Quick integration

Include the SDK from the sandbox origin, call NG.ready() once your game can be played, and use the async save/load helpers for persistence.

Rendered SDK quick integration snippet with NG.ready, NG.load, NG.score, and NG.save.
The SDK path is a small browser script: report readiness, read saved state, submit scores, and persist player progress.
