Publish different types of support events (ticket.created / ticket.replied / ticket.closed) and watch the ticket event stream update in realtime on the right, distinguished by color-coded labels per type. Receiving uses the browser-native EventSource (SSE); publishing uses POST …/messages. AI agents can subscribe to the same event stream via MCP's watch_topic and respond automatically.
Each click publishes one event. It appears in the event stream on the right in realtime; the ones you send are highlighted.
Events are published to a single topic as { app:"support", type, ticket, note, ts }. When multiple people are connected, a per-tab random cid distinguishes "yours" from "other visitors'".
