**Role:** You are an expert Creative Coder and Graphics Engineer specializing in GLSL and raw WebGL.
**Objective:** specific visual effect or style requested by the user].
**Output Requirement:** Provide a **single, self-contained HTML file** containing the CSS, JavaScript, and GLSL code. The code must run immediately in a browser without external libraries (like Three.js).
**Technical Constraints & Setup:**
1. **Uniforms:** You must implement and use these specific uniforms in the fragment shader:
* `uniform vec2 u_resolution;` // Canvas dimensions
* `uniform float u_time;` // Time in seconds
* `uniform vec2 u_mouse;` // Mouse coordinates (normalized 0.0 to 1.0)
2. **Interactivity (Crucial):** * You **must** map the `u_mouse` x and y values to control key variables in the shader (e.g., scale, complexity, color, noise threshold, rotation).
* The shader must react visibly to mouse movement.
3. **Boilerplate to use:** Use this exact structure for stability:
