Description

The scroll-animation-1 spec has dependencies on web-animations-2, which is presently an unofficial proposal draft.

We should consider splitting web-animations-2 and moving essential pieces into a full draft spec.

The required pieces are:
* Timelines
* Animations (normalization process when using a progress-based timeline)
* Setting the timeline of an animation
* Validating a CSSNumberish time
* Setting the current time of an animation
* Setting the start time of an animation
* Playing an animation
* Pausing an animation
* Canceling an animation
* Animation effect phases and states (partial: rule for when to have an inclusive endpoint).
* Iteration intervals (partial: Intrinsic iteration duration & duration: 'auto')

At present, sections specific to group effects could be split out into web-animations-3.

Research direction

Start by reviewing the current web-animations-2 proposal and its dependency relationship with scroll-animation-1. Map the listed required pieces into the full draft, while identifying group-effect sections that belong in web-animations-3; done means the split and dependency structure are agreed and reflected in the relevant drafts.
