 A small, dependency-free Forgejo Action that synchronizes a completed static
 website build to a dedicated Bunny Storage Zone.
 
+The runner needs Bash and Python 3.11 or newer. The action itself installs no
+packages and executes no code from the Gandalf repository.

 The deployer requires `index.html`, rejects symbolic links, compares files with
 a checksum manifest, uploads changed assets before HTML, deletes stale files
 only after successful uploads, and publishes the new manifest last.
