-WARNING — SW STREAM BRIDGE CONTRACT
-Purpose: allow chat streaming to continue while the page is backgrounded and seamlessly resume rendering when it becomes visible again. This page talks to a custom service worker using a BroadcastChannel named "chat-stream-v1". Protocol messages are: hello→hello-ack, start({id,payload}), delta({id,data}), done({id}), error({id,hint,aborted}), stop({id}), replay({id,offset}). If you rename the channel or change these message shapes, you must update sw.js to match; otherwise background-resume will break and streams may fail when the tab is hidden.
