⚙ Backend & cookies
Deploy media-backend/ to Render (free) — see its README. The hub can't download videos without it.
Sent per request; the server deletes per-request copies right after. “Save to backend” stores them once so every device works.
No app/extension needed — works on a locked Chrome-only phone:
1. Open a new Chrome tab → go to chrome://net-export
2. Set capture mode to “Include cookies and credentials”
3. Tap Start Logging → choose a save location
4. New tab → open youtube.com (signed in), let it load
5. Back to the net-export tab → Stop Logging → when asked, Save to Google Drive
6. Tap the button below and pick that .json log from your Drive:
On a phone, net-export saves the log to Drive — pick it here, no file upload needed.
…or pick a local .json file (desktop)
The log is read in your browser — only the extracted YouTube/Google cookies are kept; nothing else leaves your device.
