+// Glitch Effect - Chromatic aberration with CRT scanlines
+// Windows open/close with RGB channel splitting and scanline overlay
+//
+// Adjustable parameters:
+// - split (0.04): RGB split intensity - higher = more separation
+// - scanline (0.08): Scanline visibility - higher = more prominent
+// - uv.y * 400.0: Scanline density - higher = more lines
