/**
 * cursor-glow-effect.ts - Pointer-driven cursor glow effect
 *
 * Attaches pointer listeners to an element and sets CSS custom properties:
 *   --glow-x        (cursor X relative to element, in px)
 *   --glow-y        (cursor Y relative to element, in px)
 *   --glow-opacity  (0 when inactive, 1 when hovering)
 *   --glow-size     (glow radius in px)
 *
 * The consuming CSS renders the glow via a pseudo-element or overlay div
 * that reads these variables in a radial-gradient.
 *
 * Skips touch pointers. Respects prefers-reduced-motion.
