/* ============================================================
   现代墨斋 · Ink Atelier (final layer, v3 default view)
   设计决策:
   - 漆面全幅照片退场 → 宣纸场(暖米白渐变 + feTurbulence 纸纹,
     照片仅以 ~5% 残影留在纸下,作为"记忆里的墨")
   - 墨绿为骨,朱砂为印:vermilion 只给主 CTA / 关键激活态 / 印章
   - 卡片 = 案上纸:暖白 + 1px 发丝边 + 墨绿色调阴影(不用黑影),
     外容器圆角软、内控件圆角紧
   - 展示字:霞鹜文楷(自托管 GB2312 subset,1.5MB,font-display:swap,
     加载失败回落宋体系,离线可用)
   - 本层只覆写 v3(data-v3="on")默认视图;v1 古朴 / v2 墨韵不受影响

   #8: DARK MODE
   ----------------------------------------------------------------------------
   There was none: 7,400 lines of CSS with zero prefers-color-scheme, so a
   text tool people use at night was a permanently bright cream page.

   v3 (the default skin) derives every surface from two token layers —
   --at-* (墨斋 palette) and --s3-* (seasonal) — and remaps the legacy
   --ink/--panel/--line tokens from them. Redefining those layers therefore
   re-themes the whole app without touching component rules.

   Three states, per the usual contract:
     :root                         → light (defined above, untouched)
     prefers-color-scheme: dark    → dark, unless the user forced light
     [data-theme="dark"|"light"]   → explicit user choice always wins
