Advanced AI Prompt for Liquid Distortion Cursor via WebGL Shaders

Act as a WebGL/GLSL Shading Architect. Architect an elite, Awwwards-winning custom cursor interaction that utilizes a custom fragment shader to physically distort the pixels of the background image [TEXTURE_URL] acting as a liquid lens. Utilize Three.js or OGL. The vertex/fragment math must calculate a fluid ripple displacement driven by mouse velocity, governed by a [VISCOSITY] drag parameter, while violently tearing the Red, Green, and Blue color channels apart based on the [RGB_SHIFT_STRENGTH] vector. Provide the exact raw GLSL Vertex and Fragment shader strings. You must mandate and code a strict 'low-power mode' JavaScript fallback that completely destroys the WebGL context and replaces it with a simple CSS `border-radius` circle if a mobile device user-agent or low FPS average is detected, saving the user's battery life.
