   SYBER — 2026 3D redesign layer. Loaded AFTER styles.css so it overrides the
   base rules: dark WebGL hero stage (scene.js paints #webgl), aurora glow,
   animated gradient text, glassmorphism, glow buttons, 3D card tilt, scroll
   motion. Degrades: no WebGL / reduced-motion → aurora + gradient show through.
