Designers see performance as a constraint, or as a checklist item: βdonβt forget the spinner.β What if we saw it as a design opportunity instead? This talk explores what developers should expect from their designers and how to ask for it. @stephaniewalter.bsky.social at perfnow.nl

Bramus is working on new ways to make view transitions easier to handle in an MPA scenario. This is in its very early stages, but look at this funky CSS. He's looking for feedback, too! https://www.bram.us/2026...
