- Reorder HandleGameEvents to create NATS subscriptions before SSE - Use chi's middleware.NewWrapResponseWriter for proper http.Flusher support - Add slog-zerolog adapter for unified logging - Add ErrorLog to HTTP server for better error visibility - Change session Cookie.Secure to false for HTTP support - Change heartbeat from 15s to 10s - Remove ConnectionIndicator patching (was causing PatchElementsNoTargetsFound) The key fix was using chi's response writer wrapper which properly implements http.Flusher, allowing SSE data to be flushed immediately instead of being buffered.
