/* ============================================================================
 * public/bossmusic.css —— 「老板AI音乐」样式（2026-09-18 · 开发员17号）
 *
 * 独立文件、排在 style.css 之后加载（铁律：改别人的样式别动 style.css）。
 * 前缀 bmu-（bm- 已被别的功能占用 71 处，别用）。
 *
 * 设计取向：老板板块其余卡片是暖橙浅底，音乐这块做成**深墨 + 暖金**（黑胶唱片的质感），
 * 一眼能认出"这是音乐"，又不会跟站点主色打架。
 * ========================================================================== */
