/* Color of Sound — Android API 22 / old WebView compatible CSS
   Intentionally avoids:
   - CSS Grid
   - aspect-ratio
   - min()/max()/clamp()
   - CSS custom properties
   - prefers-reduced-motion
   - modern layout dependencies

   The SVG viewBox handles the square composition and centers it inside
   whatever screen shape the device has.
