Nex Max Upgrade

Build a high-performance, agency-grade Pricing section called "Nex Max Upgrade" in React 19, TypeScript, and Tailwind CSS with Framer Motion.

## 1. Overview & Visual Objective
Build a single full-viewport React + TypeScript section (Vite, Tailwind available but styles written via a <style> block) that renders a fixed background video with a pricing-style glass card overlay. The video must play back and forth in a boomerang loop via throttled manual seeking (no native .play()).

Visual Aesthetics & Mood:
fixed zoomed-in boomerang video background reverse-seek playback frosted glass pricing card overlay dark cinematic smooth ping-pong motion translucent surfaces premium sleek layered minimal polished

## 2. Technical Stack & Dependencies
- Framework: React 19 + TypeScript + Vite
- Styling: Tailwind CSS v4 + Lucide React icons
- Animation Engine: Framer Motion (layout animations, spring physics, scroll-linked parallax)
