AI Workflow Agents

Build a single-page hero landing page for a product called "Axon" — a platform that deploys digital workers for mundane workflows. The page is a full-viewport hero section with a looping background video and overlaid content.

**Fonts:**
- Load Google Fonts: `Instrument Serif` (regular + italic) and `Inter` (weights 400, 500, 600).
- Body font: `Inter`, color `#1B133C`.
- Heading font: `Instrument Serif`.

**Page structure (single full-screen section, 100vh):**

1. **Navigation bar** — centered at the top with `pt-4 md:pt-6` padding. A horizontal nav pill with `bg-white/70 backdrop-blur-md rounded-xl px-4 md:px-6 py-3 shadow-sm`. Contains:
   - A custom SVG logo (two geometric arrow/chevron shapes in `#1B133C`, 24x24px). The SVG paths are: `M 256 256 L 128 256 L 0 128 L 128 128 Z` and `M 256 128 L 128 128 L 0 0 L 128 0 Z` inside a 256x256 viewBox.
   - Navigation links (hidden on mobile, shown `sm:` and up): "Features", "Plans", "Security", "About" — styled as `text-sm font-medium text-[#1B133C]/80` with hover transition to full opacity.
