+"""YouTube cookie manager for Shanty.
+
+Manages a persistent Firefox profile for YouTube authentication.
+Handles interactive login (via Xvfb + x11vnc + noVNC), headless cookie

+
+Dependencies (runtime):
+    - firefox-esr
+    - xvfb, x11vnc, novnc, websockify (for interactive login only)
+    - sqlite3 (Python stdlib)

+    cookie_manager.py login-stop
+    cookie_manager.py refresh <profile_dir> <cookies_output>
+    cookie_manager.py export <profile_dir> <cookies_output>
