/*
 * SHOWCASE MOTION SYSTEM (v1.0, 2026-11-07)
 * ---------------------------------------------------------------
 * Micro-interactions + lightbox untuk seluruh portofolio:
 *  - Cursor glow (desktop, pointer halus).
 *  - Tombol magnetik (class .magnetic dipasang JS).
 *  - Tilt 3D saat hover pada kartu Projek & Layanan — tilt hanya
 *    di :hover supaya tidak bentrok dengan animasi reveal AOS
 *    (data-aos) yang juga memakai transform.
 *  - Lightbox preview untuk tombol "Lihat" projek (href="#").
 * Palet tetap navy + cyan situs.
