Cursor Spotlight CTA

Build a closing CTA section on pure black where a soft violet radial spotlight (300px) follows the cursor via CSS custom properties updated on mousemove (throttled with requestAnimationFrame). On touch devices the spotlight drifts on its own. Centered headline, muted subline, outlined button with a subtle glass border.
