• Layout: alternate module layout when overrides exist
• Module Class Suffix: extra CSS classes on the footer root
• Additional CSS: optional rules scoped to #jx-ffooter-{moduleId}. Unsafe patterns such as script tags and expression() are stripped.

After render, the footer and spacer are moved to document.body. That avoids transformed or overflow parents in the template that would otherwise make position: fixed behave like a relative box inside the module position.
