🎓 Key Learnings

Tailwind v4 Syntax: Uses @import "tailwindcss" instead of @tailwind directives
No @apply: Tailwind v4 doesn't support @apply in the same way
ES Modules: Requires "type": "module" in package.json
Custom Prose: Need manual CSS for markdown styling
Responsive Design: Utility classes make responsive design much faster
