/* ═════════════════ HCOS · 深色毛玻璃设计系统 ═════════════════
   窗口部分尽量模仿 Win10：直角窗口、纯平实色铬区（无渐变无毛玻璃）、
   激活窗口一圈主题色细边、标题栏与工具栏同色无缝、全高方形窗口按钮、
   输入框是比底更亮的实色块；层级只靠 1px 实色发丝线与轻微明度差
   主题色仅用于选中/按钮等交互高亮，可通过 --accent 切换
   毛玻璃分层规则（不要到处乱用，按层级给强弱）：
   · 弹出浮层（开始菜单/右键菜单/Kimi 面板/通知/toast/模态框）：强毛玻璃 blur(28px)
   · 任务栏（常驻系统层）：blur(24px)
   · 窗口（大面积工作区）：Win10 式不透明纯色分层，不用 backdrop-filter，
     内容清晰、性能也更好，实底窗口与透底浮层形成质感对比                    */
