CodeNest Coding Platform

Create a high-end, dark-themed hero section for a coding education platform called 'CodeNest' using React and Tailwind CSS. The design must be responsive and follow these precise specifications:

1. Background & Layout:

Background: Implement a full-screen background video using the HLS stream: https://stream.mux.com/tLkHO1qZoaaQOUeVWo8hEBeGQfySP02EPS02BmnNFyXys.m3u8. Use hls.js and set enableWorker: false to ensure stability in sandboxed environments.

Overlays: Set the video to 60% opacity. Add a dark linear gradient from the left (#070b0a to transparent) and a bottom-up gradient for readability.

Grid System: Add three thin vertical grid lines (white/10 opacity) at the 25%, 50%, and 75% marks across the screen (visible on desktop).

Central Glow: Place a large horizontal SVG ellipse glow in the center-top area with a cyan/dark green hue, using a 25px Gaussian blur filter.
