The new View Transition API and scroll-driven animations are just wonderful. It's such a shame that Firefox is missing that feature, but anybody using a WebKit-based browser will have the smooth transitions between pages along with images moving into place between pages, and the scrolling animation when scrolling through Upscaler's website.
(I don't currently have the time to write an alt text for the screen recording, so I'm adding #ALT4me to this post. I'll write the alt text later if no one has.)
