I saved the changes from the code editor.

The issue is clear: the globals.css file has a @apply glass-card rule that references a utility class that doesn't exist yet because Tailwind v4 doesn't support @apply with custom classes defined in the same file in the same way. Let me read and fix the globals.css:

Found the issue - the .glass-card-hover class is using @apply glass-card which references a custom class defined in the same @layer components block. In Tailwind v4, you can't use @apply to reference classes defined in the same CSS file. Let me fix this by inlining the styles:

Fixed the CSS error by inlining the glass effect properties instead of using @apply glass-card, which isn't supported in Tailwind v4 for custom classes defined in the same file. The site should now load correctly with the dark theme and all glass card effects working properly.
