View transitions

Page one. Navigate to page two: with the <meta name="view-transition" content="same-origin"> opt-in, the swap cross-fades.

Type here, then navigate. This input is data-webjs-permanent, so its value survives the swap:

Go to page two Home

Opt in app-wide instead by putting the meta on the root layout. Keep the transition simple: toggling root attributes mid-nav can cause a one-frame repaint flash on iOS WebKit.
