+## 🛠️ Robust HTML Title Extraction
+
+### `get_title_streaming(url)`
+
+This function fetches the HTML from a URL and extracts the page title using all the most common conventions, in this order:
+
+1. `<meta property="og:title" content="...">` (Open Graph, for social sharing)
+2. `<meta name="twitter:title" content="...">` (Twitter Cards)
+3. `<meta name="title" content="...">` (sometimes used for SEO)
+4. `<title>...</title>` (the classic HTML title tag)
+
+It returns the **first** found value as a string, or `None` if no title is found. All extraction is done with BeautifulSoup for maximum reliability and standards compliance.
+
+#### Example usage:
+```python
+from pstuts_rag.utils import get_title_streaming
+url = "https://example.com"
+title = get_title_streaming(url)
+print(title)  # Prints the best available title, or None
+```

+
+### 🥣 Requirements

+  ```bash
+  pip install beautifulsoup4
+  ```
