Viewer analytics, bitrate, and dropped frames
Cloudflare Stream's live-input API (what streamHealth above polls) only reports connection state -- idle/connected/disconnected -- not per-stream viewer count, delivered bitrate, or dropped frames. That data lives in Cloudflare's separate Stream Analytics product, which is minute-granularity aggregate reporting, not a real-time control-room feed, so it hasn't been wired in here. Nothing on this panel fabricates a number in its place.
