+// However, the `fetcher` I injected doesn't use useCallback, and SWR's fallback/refresh
+// logic might be triggering too aggressively because of how the subcomponents remount
+// or because `refreshInterval` is fighting with `mutatePlan(newPlan, false)`.
+
+// Let's remove the 15-second auto-polling. If the user edits something, we trigger a revalidation.
+// If the AI edits something from the chat, we already have an SSE 'plan' event that 
+// streams the update directly to the UI! So we don't need SWR to poll AT ALL.
