Advanced AI Prompt for Custom Cursor with Progress Ring Integration

Act as a UX Micro-Interactions Developer. Create a highly functional custom cursor that replaces traditional UI loading states with an integrated 'hold-to-confirm' progress ring. The cursor must feature a pristine SVG `<circle>` path that visually 'fills' its circumference with [RING_COLOR] at a thickness of [STROKE_WIDTH] exactly over the duration of [CLICK_DURATION] milliseconds while the user holds the `mousedown` event. Drive the animation entirely by mathematically interpolating the CSS `stroke-dashoffset` property. Inject critical logic to instantly abort and reverse the animation if the user triggers a `mouseup` or moves the mouse away before the timer completes. You must embed W3C-compliant ARIA live regions (`aria-live='polite'`) to audibly notify screen reader users of the ongoing 'hold' progress and the final completed action.
