+# Enable Clear Session Button in Pack Generator
+
+## Object
+Enable and improve the "Clear Session" button in the Cube Manager (Pack Generator) to allow users to restart the generation process from a clean state.
+
+## Changes
+- Modified `CubeManager.tsx`:
+    - Updated `handleReset` logic (verified).
+    - enhanced "Clear Session" button styling to be more visible (red border/text) and indicate its destructive nature.
+    - Added `disabled={loading}` to prevent state conflicts during active operations.
+    - **Replaced `window.confirm` with a double-click UI confirmation pattern** to ensure reliability and better UX (fixed issue where native confirmation dialog was failing).
+
+## Status
+- [x] Implementation complete.
+- [x] Verified logic for `localStorage` clearing.
+- [x] Verified interaction in browser (button changes state, clears data on second click).
