@Meyerweb it animated `display: none` in the vid which isnt something `transition` can do, but i hear ya here

i see it less as a capability, in this demo, and more of a smoother transition between code edits; you get to watch your work animate into the final state. not jarring or instant, it interpolates to whatever you most recently defined. all with 1 API call to tell the browser you're about to change stuff.

it's also keyframes and not a `transition`, which is a distinction and limitation
