A home page that holds still while it plays
The home page replays no longer nudge the page as they run, phones get their layout from the first paint, and cards and links read more clearly.
Nothing jumps
The app window on the home page plays a real run, and each new step used to push the earlier ones up by moving them in the page. Browsers count every one of those moves as the page shifting under you. The chat now slides as one piece, so the picture is the same and the page stays put.
On a phone the window and the sub-agents graph used to arrive in their desktop shape and switch to the narrow one a moment later, pushing the text below them down. Both now take their phone shape before anything loads, and the page measures zero layout shift on phones and desktops.
Easier to read
In the undo card, the lines a run added are struck out when you undo it instead of fading almost to nothing, and the struck-out version stays readable. The approval note and the models list have more contrast. Links inside sentences, like the one to Learn under the questions, are underlined, so they no longer rely on colour alone. The skip link on Learn, Shipped and Changelog pages now lands on the content.
