   预设 P19「玄铁赤焰」—— 冷铁灰黑底 + 猩红主色 + 骨白正文
   目标形态 = 腾讯系端游官网：朴素、信息密度高、玩家一眼认得。
   ---------------------------------------------------------------------------
   ★ 变量命名说明（2026-08-23 一次性修好的历史坑）
     本文件的变量名从前是从克隆源带过来的，名字和取值完全对不上
     （曾经 --blood 是绿色、--gold 是紫色）。本次改版**全部改成语义名**：
       --accent      主强调色（猩红，唯一的主 CTA 色）
       --accent-hi   主强调色·亮（hover / 高亮文字）
       --accent-dim  主强调色·暗（边框 / 分隔 / 次级块）
       --ink         正文主色（骨白）
       --muted       次要文字   --faint 更弱的文字
       --bg/--bg-2/--panel/--panel-2  由深到浅的四层底
     以后改色只改 :root，别再往下面塞硬编码色值。
   ---------------------------------------------------------------------------
   ★ 视觉基调：降饱和、少发光。阴影一律走 --shadow / --shadow-sm，
     发光只留主 CTA 一处很轻的 --glow。靠大图 + 排版层级撑场子，不靠荧光。
