+### 1.3 **`status_code`** *(Optional[int])*
+**What**: The page's HTTP status code (e.g., 200, 404). When the page was reached via redirect, this is the status code of the **first** response in the redirect chain (e.g., 301 or 302).
 **Usage**:
 ```python
 if result.status_code == 404:
     print("Page not found!")
 ```

+### 1.4 **`redirected_status_code`** *(Optional[int])*
+**What**: The HTTP status code of the **final** redirect destination. For a 302→200 redirect, `status_code` is 302 and `redirected_status_code` is 200. `None` for non-HTTP requests (raw HTML, local files).
+**Usage**:
+```python
+if result.status_code in (301, 302) and result.redirected_status_code == 200:
+    print(f"Redirected to {result.redirected_url} (OK)")
