 ## Phase 1: Robust Shader & FBO Foundation
 - [x] Task: Implement: Create `ShaderManager` methods for downsampled FBO setup (scene, temp, blur). [d9148ac]
 - [x] Task: Implement: Develop the "Deep Sea" background shader and integrate it as the FBO source. [d85dc3a]
-- [ ] Task: Implement: Develop the 2-pass Gaussian blur shaders with a wide tap distribution.
