/**
 * Magnetic Gravity Grid – front-end styles
 *
 * Opbouw (elk niveau heeft precies één verantwoordelijkheid, zodat de
 * transforms elkaar nooit overschrijven):
 *
 *   .mgg-item      → grid-cel, geen transform
 *   .mgg-magnet    → JS: magnetische verplaatsing + "ruimte maken" voor buren
 *   .mgg-float     → CSS: continue ambient zweef-animatie
 *   .mgg-card      → JS/CSS: hover-schaal + 3D tilt
 *
 * Alle instelbare waarden komen binnen als CSS custom properties vanuit PHP.
