✅ Migration Complete: Tailwind CSS v4 + PrimeVue v4

🎉 Successfully Converted!

Your AI project has been fully migrated to use:

• Tailwind CSS v4 (latest version with new CSS-first configuration)
• PrimeVue v4 (latest Vue 3 UI component library)

🔧 What Was Fixed

1. Tailwind CSS v4 Setup

• ✅ Installed @tailwindcss/postcss (new PostCSS plugin for v4)
• ✅ Updated postcss.config.js to use @tailwindcss/postcss
• ✅ Converted main.css to use @import "tailwindcss" (v4 syntax)
• ✅ Simplified tailwind.config.js (v4 uses CSS-based config)
• ✅ Added @theme directive for custom theme values

2. PrimeVue v4 Setup

• ✅ Fixed import path: primevue/themes/aura (not @primevue/themes/aura)
• ✅ Configured Aura theme with dark mode support
• ✅ Set up CSS layer ordering for Tailwind compatibility

3. Case Sensitivity Issue

• ✅ Fixed import: @/models/asset (lowercase, matching filename)
• ✅ Updated Asset interface to include link property
