+    Submits the current URL to [Ghost Archive](https://ghostarchive.org/) for archiving and returns the archived page URL.
+
+    Used as an **enricher** to add a Ghost Archive URL to items already extracted by other modules.
+
+    ### Features
+    - Archives any public URL using the Ghost Archive service.
+    - Optionally checks for existing archives before submitting a new one.
+    - Supports HTTP and HTTPS proxies for requests.
+    - Parses HTML responses to extract archive URLs (Ghost Archive has no JSON API).
+
+    ### Important
+    - This module confirms that Ghost Archive accepted the URL submission and returned an archive link.
+      It does **not** verify the contents or completeness of the archived page.
+
+    ### Notes
+    - Ghost Archive is a free service with no authentication required.
+    - Archived pages must be smaller than 50 MB (including CSS, fonts, images, etc.).
+    - Videos are archived up to 360p and must be under 100 MB and shorter than 30 minutes.
+    - Archival may take up to 5 minutes depending on the queue and page complexity.
+    - Archived content is stored indefinitely.
+    - Ghost Archive does not archive pages that require authentication or form submission.
+
+    ### Limitations
+    - No official API — this module interacts with the Ghost Archive web interface.
+    - The submission endpoint is protected by Cloudflare, so a headless browser (SeleniumBase) is used for new submissions.
+    - Searching for existing archives uses plain HTTP requests and does not require a browser.
+    - Rate limiting may apply; consider using a delay between requests if archiving many URLs.
