Neon Logic

Build a single-page landing site for "SynapseX" -- a futuristic neural-AI interface product. The entire site uses a black background with white text and full-viewport video backgrounds. The primary font is "Space Mono" (monospace) for all text. Use React + TypeScript + Vite + Tailwind CSS + Framer Motion.

### Fonts & External Assets

- **Primary font:** "Space Mono" (all weights: 400, 700, italic) from Google Fonts
- **Display font (background watermark only):** "Anton SC" from Google Fonts
- **Icons:** Bootstrap Icons CDN (`https://cdn.jsdelivr.net/npm/bootstrap-icons@1.11.3/font/bootstrap-icons.min.css`) -- used only for the Apple icon (`bi bi-apple`) in the download button
- **All Tailwind `fontFamily` keys** (`sans`, `serif`, `mono`) are overridden to `"Space Mono", monospace`

### Video URLs (CloudFront -- use exactly these)
