/* Trường Nguyễn Music V241 BETA – Playlist Catalog album-geometry parity.
 * Scope: ONLY /kho-playlist, no homepage, Album, Angular Player or Admin styles.
 * Geometry: matching existing tn-music-v1.css expanded ALBUM catalogue:
 * 5 columns, 18px gaps, square artwork, 11px radius, 13px title, same content gutter.
 * Slider above uses the existing V146 multi-zone renderer and Admin playlist setting.
