/* blog.manana.icu —— 视觉语言复刻自 LBEILC/RhineLabUI（MIT）的「档案终端」质感。
 *
 * 依据（本地克隆 G:\refs\RhineLabUI，逐条对着它的实现抄，不凭印象）：
 *   · :root   → font-family: "MiSans", …, color: #080a08, background: #e8e5e1
 *                ⇒ **纸白底 + 近黑字**（我一开始猜成暗色 ✗）
 *   · 用色频次 → #080a08(字) #e8e5e1/#ece9e4(纸) #aaa59a/#bdb8ad/#8e897b(暖灰)
 *                #a67d48/#9b7247(脏黄铜 —— 强调色，不是我之前用的亮金 ✗)
 *   · 排版刻度 → 字号集中在 9/10/11/12/13/14/15/16px（小字密排），letter-spacing 1px 用了 22 次
 *   · 结构     → 1px **可见**发丝线（#a6a49c / #8e897b / #bdb8ad / #c1b8a7），不用 0.5px
 *   · 动效     → @keyframes 只有 orbit / blink / fadeIn / detailEnter / modalEnter / loading
 *
 * ⚠️ 复刻的是**视觉语言与档案结构**，没搬它的 Three.js/WebGL（那是为 3D 模型与视频级动效
 * 服务的；给文字上 3D 引擎是纯维护负担）。皮照抄、骨髓换成我们自己的内容。
