SSE collection events on the site now. Worker distribution panel. Experiments UI. Can watch epochs promote in real time -- files go from pending to active and the UI updates without a refresh.
Should've had this months ago. I was refreshing the collection detail page like an animal. The SSE pipe was maybe 40 lines of code on the server side and another 30 on the client. Months of manual refreshing for 70 lines of code. Sigh.
