+
+            ### ⚠️ Important Notes
+
+            - **This is an automated canary build and is NOT intended for production use.**
+            - Canary builds are triggered by `build`/`fix`/`style` commits on the `canary` branch.
+            - May contain **unstable or incomplete changes**. **Use at your own risk.**
+            - It is strongly recommended to **back up your data** before using a canary build.
+
+            ### 📦 Installation
+
+            Download the appropriate installer for your platform from the assets below.
