- Core counters: messages processed, sessions, queue depth, uptime, active requests, errors
- Model performance table: recent calls with latency, tokens/sec, provider, status
- Event stream: scrollable log with color-coded levels (error/warn/info)
- Active requests: in-flight request table with session, channel, duration
- Channels grid: existing channel status cards preserved
- Dual timer refresh: 3s for metrics/events/requests, 10s for health/channels
- Targeted DOM updates via getElementById for flicker-free fast updates
