📞 Support

The new CSS maintains full compatibility with the existing HTML structure. All Bulma classes still work, but are now implemented with custom, lightweight CSS.

To revert to Bulma (not recommended):

<!-- In apps/public/inc/header.php -->
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bulma@0.9.4/css/bulma.min.css">

But the custom CSS is faster, smaller, and fully customizable! 🎉
