/* ==================== 黑胶唱片 + 唱臂探针（站长 2026-10-17）====================
 * 站长原话：「中间播放器播放时设计为黑胶碟片，探针读轨形式，类似于留声机」。
 *
 * 视觉结构：
 *   .pm-music__turntable  转盘容器（唱臂的定位基准）
 *     .pm-music__disc     黑胶唱片：一圈圈音轨纹路 + 中央封面标签 + 中心孔
 *     .pm-music__tonearm  唱臂（探针）：播放时落到音轨上，暂停时抬起
 *
 * 【纹路怎么画】用 repeating-radial-gradient 画同心圆环，一层渐变=一圈纹路，
 *   比堆一堆 div 性能好、缩放不糊。纹路用微弱高光（白 0.055），
 *   太亮会有塑料感，太暗看不出纹路。
 *
 * 【唱臂动作】待机 rotate(-32deg) 抬在唱片外；播放 rotate(0deg) 落到边缘读轨。
 *   加 transition 让落针有"缓缓放下"的手感。
