/*
  24901.org Mobile Fixes
  Ready-to-use media queries for mobile responsiveness

  INTEGRATION: Add this link to index.html before </head>:
  <link rel="stylesheet" href="/mobile-fixes.css">

  TESTING DEVICES:
  - Pixel 8 Pro: 412 x 732 CSS pixels (hits 480px breakpoint)
  - iPhone 14: 390 x 844 CSS pixels (hits 480px breakpoint)
  - iPhone SE: 375 x 667 CSS pixels (hits 375px breakpoint)

  BREAKPOINTS: 768px (tablet), 480px (primary mobile), 375px (ultra-narrow)

  NOTE: Globe (Three.js) is NOT modified — it handles its own resize via
  container.clientWidth/Height. The globe fills the hero section on all devices.
