🎨 Fix CSS: Import global.css + plain CSS styles

CSS was not being imported! Fixed:

✅ Added 'import ../styles/global.css' to BaseLayout.astro
✅ Rewrote CSS with plain CSS (not @apply which wasn't working)
✅ Cookie banner has inline styles as backup
✅ Font size: 16px base
✅ Solid colors: green-600 (#16a34a), gray-900 (#111827)
✅ Footer has policy links

Build: 12 pages ✅
