Summary
- Native browser keyframe animations with deterministic seeking for HyperFrames compositions.
- Create animations synchronously with element.animate() using finite durations and iterations, then pause them for adapter control The adapter seeks all active animations via document.getAnimations() by setting currentTime to HyperFrames timeline position in milliseconds Use fill: "both" to persist seeked states, and model clip timing with delay or visibility control rather than relying on clip-local start times Supports staggered animations, keyframe offsets, and easing functions; avoid infinite iterations, animation.finished callbacks, and layout property animation
