Performance Eyewear

Build a high-performance, agency-grade Ecommerce section called "Performance Eyewear" in React 19, TypeScript, and Tailwind CSS with Framer Motion.

## 1. Overview & Visual Objective
Build a single-page vanilla HTML/CSS/JS site (no frameworks, served via Vite) for a luxury performance eyewear brand called "Orven". The entire page is a scroll-driven hero experience with two video scrub phases and animated text reveals. Black background, white text, all elements use `mix-blend-mode: difference` to remain visible over any video frame.
