/* ============================================================
   换肤扩展层（themes.css · 20260924a）
   原则：不动 style.css 一行；通过 html[data-theme] 覆盖 CSS 变量
   + 定向覆盖 style.css 中的浅色硬编码（背景/软底/条纹）。
   主题：dark-purple 暗夜紫 | nike-mono 黑白大写 | terminal 终端单色
   图表：深色主题下 ECharts 画布仍按浅色渲染，故给 .chart 容器
        白色衬底，作为深色界面中的"浅色图卡"，观感刻意保留。
