/* 人体专业知识 · 改善推进（improvement）路由样式
   来源：素材/Human-Professional-Knowledge modules/improvement.css 全部 improvement- 规则
        + styles/95-brand-visual-unification.css 中 improvement- 相关最终覆盖（圆角/按钮/输入/徽章），已按最终合成效果合入。
   适配：模块 monochrome-dark-v1 灰阶体系（--hk-panel/--hk-panel-secondary/--hk-border/--hk-border-strong/--hk-muted/--hk-strong/--hk-faint）。
   映射约定：面板/边框/正文 → --hk-*；原版浅底成对配色（如 #242424+#e5e5e5、#242424+#b3b3b3 徽章与按钮）为自洽配色对，成对保留原值；
   原版浅底上的裸强调文字（#e5e5e5/#b3b3b3/#e5e5e5 系）在暗底下提亮为 --imp-accent/--imp-green/--imp-red。
   结构差异：原版为 app-shell 内 100vh 双栏内滚布局，此处改为模块常规文档流（同 process-route）；侧栏主题按钮/各跳转按钮由 <button> 改 <a>，样式等价。 */
