NexaCore

Build a React + TypeScript + Vite + Tailwind CSS landing page for "NexaCore" — an enterprise infrastructure operations platform. Use lucide-react for icons, hls.js for HLS video streaming, and @supabase/Bolt Database-js (available but not yet wired). No other UI libraries.

Global Setup Fonts (src/index.css) Load "Mazzard H" custom font via @font-face before Tailwind directives:
