This folder must contain fut-auto-buyer.user.js before the extension can load the worker.

Do not copy it by hand. Run from the repository root:

    powershell -ExecutionPolicy Bypass -File scripts\package-extension.ps1

The script copies release\fut-auto-buyer.user.js (or eafc\static\fut-auto-buyer.user.js),
strips the userscript header, blanks any hardcoded pairing token, and builds the zip.
The generated bundle is git-ignored.
