Advanced AI Prompt for SDF-Based Kinetic Typography

Act as a WebGL Typography Architect. Develop a specialized WebGL shader strictly engineered for rendering high-performance kinetic typography utilizing Signed Distance Fields (SDF). The system must map UV coordinates to a pre-rendered [FONT_ATLAS] texture, leveraging SDF math to render infinitely sharp, crisp text at any scaling dimension. Program a violent, wave-like vertex displacement function operating at a [WAVE_REPETITION] frequency, combined with a severe [SKEW_ANGLE] shear matrix that physically reacts and intensifies based on the DOM scroll velocity. Construct a procedural [SHADOW_OFFSET] directly within the fragment shader by sampling the SDF texture a second time at a shifted coordinate, creating a deep, faux-3D drop shadow effect. You must aggressively optimize the SDF contour sampling by utilizing the GLSL `fwidth()` function to achieve perfect hardware-level antialiasing.
