Advanced AI Prompt for SVG Path-Following Cursor Trail

Act as a Vector DOM Manipulator. Design a breathtaking custom cursor interaction that physically paints a continuous, trailing SVG `<path>` line directly across the screen, mapping the exact, chaotic movement history of the user's mouse. The drawn vector path must be styled with a kinetic [STROKE_DASHARRAY] dotted pattern and radiate an intense [GLOW_COLOR] CSS `filter: drop-shadow` neon effect. To prevent the DOM from violently crashing due to thousands of coordinate points, you must engineer a highly aggressive array-splicing function that strictly limits the stored history to the last [TRAIL_LENGTH] (e.g., 20) raw X/Y coordinates. Construct a `requestAnimationFrame` loop that rapidly re-writes the SVG `d` attribute string (`M x y L x y...`). Provide the specific garbage-collection logic required to detect when the mouse has been idle for 500ms and smoothly dissolve/purge the entire SVG path from the screen.
