  <!--
    NOTES:
    - Individual simulation pages are served via viewer.html with query parameters
    - They are discoverable through the homepage and category pages
    - If you want to list all 78 simulations individually, you can generate URLs like:
      https://[YOUR-DOMAIN-HERE]/viewer.html?cat=Mechanics&file=Projectile%20Motion%20Simulation.html
    
    - Private/Admin pages are excluded:
      * dashboard.html (admin only)
      * signin.html (utility page)
      * signup.html (utility page)
      * my-dashboard.html (user dashboard)
    
    - To auto-generate individual simulation URLs, run:
      node generate-sitemap.js (if you create this script)
  -->
