Create a fullscreen hero section for a SaaS product called "flowpath" using React, Tailwind CSS, and Lucide React icons. The section should be a single `<section>` filling the viewport (`h-screen w-full overflow-hidden`).

**Background:**
- A looping, muted, autoplaying `<video>` element covering the full section with `object-cover`. Video URL: `https://d8j0ntlcm91z4.cloudfront.net/user_38xzZboKViGWJOttwIXH07lWA1P/hf_20260703_053131_1ec3dd1c-d627-44fb-ab20-6e1fce41b0d5.mp4`
- A subtle dark overlay on top of the video: `bg-black/10`

**Font:**
- Use "Helvetica Now Text" as the primary font, loaded from: `https://db.onlinewebfonts.com/c/08e020de1811ec4489f82d1247a42c09?family=Helvetica+Now+Text`
- Fallback stack: `-apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, sans-serif`
- Applied globally via `* { font-family: ... }` in CSS
