/* A · 黑金 —— 維港夜景 × 金融大屏。深藍黑底、金色細線、不透明面板、圓角方塊號碼
 *
 * 【性能策略（無顯卡 / 遠程桌面環境）】特效外觀保留，改用 CPU 友好的實現：
 *   1. 去掉 backdrop-filter（毛玻璃）→ 不透明漸變面板，視覺幾乎一致
 *   2. 去掉 background-attachment: fixed、大半徑 box-shadow / drop-shadow / text-shadow
 *   3. 倒數進度只寫在進度環自身（--p），不再寫在 <html> 上觸發整頁樣式重算（見 app.js）
 *   4. 號碼：單層線性漸變 + 內陰影，不用多層徑向漸變與外發光
 *   5. 自動省電：卡頓時給 <html> 加 .lite（見 theme.js），再關閉裝飾性特效
