Introducing view-transitions-toolkit, a collection of utility functions to more easily work with View Transitions.

It includes helpers for feature detection, shimming document.activeViewTransition, extracting and optimizing animations, controlling transition playback (pause/resume/scrub), and automatically injecting transition types based on navigation.
