/* 星梦Staream · 晴蓝樱粉梦境
   取色参考：奶油白底、晴蓝发与樱粉发的水彩晕染、斜向逆光、飘落花瓣。
   玻璃降低白色填充、加大透色与折射高光，让天空的水彩能透进来。
   暖黄比上一版更明确：以大面积雾晕托底 + 胖星柔光 + 模糊流星的黄光，
   仍然不做高饱和实体色块。全站星形统一为圆角五角星 SVG（symbol #puffy-star）。
   性能：静态水彩全部改用渐变烘焙，去掉全屏 backdrop-filter 与大面积 filter；
   星星 / 白花动画只用 transform+opacity，滚动监听用 requestAnimationFrame 节流。
   本版：漂移改四点弧线并加大位移与旋转；新增偶尔掠过、留下渐隐光迹的流星；
   蜜金雾晕面积放大并用多段渐变柔化边缘；星夜底色压暗一档托住亮色文字。
   流星统一从右上掠向左下，头部飞出屏幕才熄灭；光迹细线两端收透明、外叠宽雾。
   本版：流星飞行段略放宽（稍慢）、光迹更快淡出；极小小星改为静态只留明暗层次；
   背景爱心由淡蓝改为樱粉，晴空与星夜分别取色。
   本版：流星再放慢一点；光迹右端锚定头部、只向走过的后方延伸，慢速流星的头部改到行进前方；
   全站星形统一为圆角五角星（移除四角星芒）；按评审补对比度、移动端减负、窄屏断点与 SVG 主题图标。
   本版：星星生成时随机一个朝向、之后只平移不旋转；白花旋转幅度加大；花/星/爱心位移再放大一档。
   本版：星夜的蓝色小字与符号改近白冷调并加极淡暗描边，玻璃面板由透白改透深蓝紫，
   让 12–14px 的细笔画在夜空里也站得住；白天模式配色完全不动。
   本版：内容区铺满屏宽并给正文留舒适行宽；导航换行不裁切；强调色文字改用深色版过 AA；
   补无脚本兜底与分享元信息；窄屏关闭实时毛玻璃；新增版本日志文章与关于页 HTML 预览。 */
