Add Static Demo Version for Easy Deployment and Sharing

[Copilot]

🎯 Overview

This PR adds a complete static demo version of the Airport Turbulence Visualization that can be deployed to platforms like surge.sh or GitHub Pages without requiring any backend infrastructure.

✨ New Features Added

📁 Static Demo Directory (/static-demo/)

• Complete standalone version that runs entirely in the browser
• No backend dependencies - perfect for quick sharing and demos
• Professional deployment-ready with comprehensive documentation

🌍 Core Functionality

• Full 3D WorldWind Globe: Interactive visualization with atmospheric effects
• 8 Major Airports: LAX, JFK, ORD, DFW, ATL, SFO, SEA, MIA with realistic data
• Real-time Simulation: Mock data updates every 30 seconds with weather variations
• Color-coded Turbulence: Green → Yellow → Orange → Red intensity indicators
• Interactive Controls: Click airports, refresh data, reset view, auto-refresh toggle

🔧 Technical Implementation

• Mock Data System (mock-data.js): Comprehensive airport data with realistic METAR-style reports
• Static API Layer (static-api.js): Complete backend simulation with proper data formatting
• Enhanced Visualizer: Fixed canvas sizing issues and improved responsiveness
• Demo App Controller: Specialized initialization and UI management for static deployment
• WorldWind Fallback: Mock implementation ensures demo works even when CDN is blocked

📚 Documentation & Deployment

• Complete Deployment Guide: Step-by-step instructions for surge.sh and GitHub Pages
• Student-friendly Setup: Enhanced from previous educational documentation work
• Professional Styling: Demo-specific UI enhancements and loading screens
• NPM Scripts: Easy deployment with npm run deploy-surge and npm run deploy-gh-pages

🐛 Bug Fixes

Canvas Rendering Issues

• Fixed oval globe distortion when maximizing browser window
• Proper canvas sizing with dynamic resize handling and high-DPI support
• Eliminated blurriness caused by CSS scaling conflicts

Data Flow Corrections

• Fixed field name mismatches between mock data (code) and visualizer expectations
• Corrected initialization sequence - app wasn't being initialized on page load
• Enhanced error handling and debug logging throughout the pipeline

Visual Rendering

• Fixed missing airport circles - were not appearing due to data format issues
• Proper layer ordering to prevent duplicate turbulence layer creation
• Responsive design improvements for mobile and desktop

🚀 Deployment Ready

Quick Deploy Commands

# Surge.sh (recommended)
cd static-demo
npm run deploy-surge

# GitHub Pages

Ready to merge! This static demo version maintains all the visual appeal and functionality of the full system while being incredibly easy to deploy and share. Perfect complement to the existing full-stack implementation.

Warning

Firewall rules blocked me from connecting to one or more addresses

I tried to connect to the following addresses, but was blocked by firewall rules:

• files.worldwind.arc.nasa.gov
  • Triggering command: wget -q -O /tmp/worldwind.min.js REDACTED (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
