ShaderTickerLayerState<T extends StatefulWidget> class
abstract
Hạ tầng dùng chung cho các layer full-screen chạy 1 FragmentShader
(AuroraBgLayer, NeonAuraLayer): load FragmentProgram.fromAsset với
try/catch (ẩn hẳn hiệu ứng nếu load lỗi, không crash), throttle ticker
repaint xuống ~30fps, và dispose đúng cả ticker lẫn shader.
Subclass chỉ còn phần riêng: asset path, tốc độ theo variant, và
painter/uniform-setting logic của chính nó trong build().
