/* 心流 /flow/（2026-10-27 起）。v0.26（10-29）照心流样稿 B 沉浸式改（样稿的 page.css；Leon 10-28 看样稿定）：
   当前曲目的背景图铺满整屏（.fl-bg，position: fixed，在页面最底下），播放器是沉在底部的一条磨砂条（.fb-dock），曲目表从右边拉出（.fb-drawer）；
   唱片机拿掉，字符粒子留着，按键是细线圆圈、点缀用细金色（--fl-gold），「在线咨询」照旧朱红（页头的，不在这里写）。
   这一页一律夜色（页面开头 theme: dark，build.py 第一帧前定好），所以只写夜里的颜色：底色压到 #0a0d12（近参考站的蓝黑），别的照 ui.css 夜里的变量。
   页头、页脚、导航是全站的；页脚压在背景图上面（z-index 1）。页面里不用任何 mix-blend-mode（会让页头的毛玻璃失效）。
   字：英文、数字用 Cormorant Garamond（本站的子集，只有 500、400 斜体、500 斜体三档拉丁字，只这一页加载）；
       页面上写死的中文衬线字（曲目表的「曲目」）走 var(--serif)（FyroSerif，tools/serif-font.py 按这里收字）；
       曲名以后若有中文，落到系统宋体（--fl-en 后面那几个），不用 FyroSerif（它只收了写死在页面上的字）。
   网页画中画小窗（Document Picture-in-Picture）把 ui.css 和这一份抄进小窗，所以小窗的样式（.pip-*）和小窗里的减少动态也写在这里。 */
