/*
 * DJ-Digger Viewer — Minimal Flat High-Contrast Design
 *
 * Layout:
 *   Desktop (>=1180px): single row of [controls-left | player | stats] above a
 *     4-column data grid. Components naturally pull closer as the window narrows.
 *   Mobile  (<1180px) : data grid, filters and stats are hidden. Only the
 *     VU meters, the now-playing player and the two transport buttons remain.
