/* ============================================================
 * yupoo-style.css — 仿 yupoo 视觉风格（class 名对齐参考UI）
 * 本轮重写 (2026-04-20)
 * ------------------------------------------------------------
 * 设计目标：视觉上接近 bmlinofficial.x.yupoo.com 系列页面。
 * class 名对齐 yupoo 原站（.showheader__* / .showalbum__* 等）
 * 不依赖 yupoo CDN（完全本地实现），深浅色都可控
 * ============================================================ */
