Email Landing Page

Build a premium, AI-native email client landing page called "Aura" using **React 18 + TypeScript + Vite + Tailwind CSS + motion/react (framer motion) + lucide-react**. The aesthetic is dark (bg `#0c0c0c`), cinematic, glassy, with a looping fullscreen background video, a shiny gradient headline, a macOS-style menu bar, a realistic inbox mockup, and a custom "liquid-glass" card treatment.

## Stack / setup

- `package.json` dependencies: `react`, `react-dom`, `@supabase/supabase-js`, `motion` (v12+, import from `motion/react`), `lucide-react`.
- Tailwind config extends colors with `brand: '#3D81E3'` and fontFamily sans with `['Inter','system-ui','sans-serif']`.
- Font: Google Fonts Inter weights 400, 500, 600, 700, 800, 900. Import in `index.css` via `@import url('https://fonts.googleapis.com/css2?family=Inter:wght@400;500;600;700;800;900&display=swap');`.
- `html,body { font-family: 'Inter', system-ui, sans-serif; -webkit-font-smoothing: antialiased; }`.
- Background color base `#0c0c0c`, text white, selection `bg-brand/30`.
