Stellar AI

Create a "Stellar.ai" landing page hero section using React, Tailwind CSS, and Lucide React icons. Use the Inter font (imported from Google Fonts). The page has a white background (bg-white), max-width max-w-7xl, and is centered with mx-auto.

Font: Import Inter (weights 400, 500, 600, 700) from Google Fonts. Set font-family: 'Inter', sans-serif on the body.

Custom CSS animations (in index.css):

@keyframes fadeInUp -- from opacity: 0; transform: translateY(30px) to opacity: 1; transform: translateY(0). Class .animate-fade-in-up uses this with 0.6s ease-out forwards.
@keyframes fadeInOverlay -- from opacity: 0 to opacity: 1. Class .animate-fade-in-overlay uses this with 0.4s ease-out forwards.
@keyframes fadeInDialog -- from opacity: 0 to opacity: 1. Class .animate-slide-up-overlay uses this with 0.5s ease-out forwards and has transform: translate(-50%, -50%).
Every major section uses .animate-fade-in-up with staggered animationDelay inline styles (starting at 0.1s and incrementing by 0.1s). Each element starts with opacity: 0 inline so the animation fills it to visible.

Tailwind config: Default config with no custom theme extensions. Uses standard content paths.
