 * v2.1.148 T1: 音频 CSS 拆分模块 (extracted from prototype.html)
 *
 * 来源行号(拆分前 prototype.html 13314 行,2026-06-26):
 *   - .node.audio                                  L619   (1 行,散落)
 *   - .node-head-icon[data-type="audio"]           L1773  (1 行,散落)
 *   - .node-preview.asset-audio                    L1948-1955 (8 行)
 *   - .clip.audio + .clip.audio .clip-strip        L2529-2539 (11 行)
 *   - .lightbox-audio-visual + .audio-icon         L3207-3212 (6 行)
 *   - .prop-badge.audio                            L3741  (1 行,散落)
 *   - .audio-node-card + .audio-upload-*           L4056-4188 (~133 行)
 *   - .audio-popover + .audio-popover-foot + ...   L4190-4271 (~82 行)
 *   - .audio-mode-bar + .audio-shortcut-* + ...    L4798-4875 (~78 行)
 *
 * 拆分理由:
 *   - audio JS 已独立(canvas-bundle.js + canvas-audio-renderer.js 308 行)
 *   - audio CSS 散落在 prototype.html 9 处, 集中后约 320 行
 *   - 后续 audio 域二次重构(popover 优化、播放器替换)不再动 prototype.html
 *
 * 边界:
 *   - 不改 prototype.html 其他 CSS 选择器
 *   - 不改任何 audio JS
 *   - 不引入新依赖,只用 prototype.html 顶层 <style> 已声明的 CSS 变量(--text / --muted / --border / --green / --cyan / --purple / --yellow)
