Lottie for FrameVideo

FrameVideo can seek both lottie-web and dotLottie players through its lottie runtime adapter. Lottie is a strong fit because the animation timeline is already encoded in the asset; FrameVideo only needs a player object it can seek.

Contract

• Load assets from local project files, usually under assets/.
• Set autoplay: false.
• Prefer loop: false unless the user explicitly wants a loop.
• Register every returned animation or player on window.__fvLottie.
• Keep the Lottie container dimensions stable with CSS.

The adapter seeks lottie-web with goToAndStop(timeMs, false) and dotLottie with frame or percentage APIs depending on player shape.
