ad‑animation is a lightweight NPM library that provides utility wrappers around GreenSock (GSAP) for creating and controlling animations in ad creatives. It offers a **SpritePlayer** class for frame‑by‑frame sprite sheet playback (with looping, speed, callbacks, etc.) and a **TweenPromise** helper that returns promises from GSAP tweens, making sequencing easier. The package is aimed at front‑end developers and motion designers building interactive, programmatic web ads.
