/* ==========================================================================
   Wild OS 交互演示 · 组件样式  v3
   ------------------------------------------------------------------------
   形态：一个始终不变的桌面应用窗口，三栏工作区，四个阶段发生在窗口内部。
   气质：纯白工作区 + 中性浅灰侧栏 + 近黑正文。统一 1px 细边框、克制圆角，
         不用米黄纸感、暖色台面和厚重阴影。关键判断靠细线与小标记醒目，
         不靠大片彩色。
   作用域：全部限定在 .wildos-demo 内，不触碰任何全局元素。前缀：wdos-
