Advanced AI Prompt for Frosted Glass & Bokeh Post-Processing

Act as a Cinematic Rendering Engineer. Implement a mathematically accurate Depth-of-Field (DoF) and Bokeh post-processing fragment shader specifically designed to overlay a 3D WebGL hero section. Avoid simple box blurs; you must utilize complex circular disc sampling kernels operating at a punishing [BLUR_QUALITY] iteration count to generate physically accurate lens artifacts. The shader must calculate the exact Circle of Confusion (CoC) blur magnitude by evaluating the depth buffer against a defined [FOCUS_DISTANCE] and [APERTURE] uniform. To achieve a premium 'frosted glass' aesthetic, intercept the UV sampling vectors and aggressively jitter them utilizing a high-frequency procedural white-noise function. Ensure the resulting [BOKEH_RADIUS] scales non-linearly based on depth. Provide the required pass-through vertex shader and the heavily mathematical fragment logic.
