Advanced AI Prompt for CSS Houdini Paint Worklet Patterns

Act as a Core Browser Engine Developer. Push the absolute bleeding edge of CSS by architecting a custom CSS Houdini Paint Worklet. You must write the JavaScript class extending `registerPaint` that mathematically executes the complex [CANVAS_DRAWING_LOGIC] (e.g., generating a generative, randomized Voronoi cell background or a dynamic static noise pattern) directly during the browser's native paint phase. Define the strict CSS `@property` syntax required to pass [CUSTOM_PROPERTY_INPUTS] (like colors or scale) directly from the CSS file into the JS worklet. Because Houdini support is fragmented, you must architect a flawless CSS `@supports` query serving a standard [FALLBACK_BACKGROUND] for Firefox/Safari users.
