/* =====================================================================
 * 白天模式（html.light）补丁 + 切换防闪烁 —— v20260929-3
 * 1) 上一轮（v20260929-2）只把「已变量化」的颜色跟随主题，散落在各组件里的
 *    硬编码深底 / 半透白没跟上 —— 最明显的是单图生成的「编辑结果」预览框
 *    （#1F252D）与生成历史面板（#151A21）、琴键玻璃面板（半透黑）。
 *    这里集中反转；**全部写成 html.light 覆盖，夜晚样式一字未动**，删掉整段即可回滚。
 * 2) 切换瞬间禁用全站过渡：几十处 `transition: all` 的元素渐变不同步，
 *    中途会出现「背景已浅、文字还是浅色」的错帧（用户感知就是闪一下）。
 *    app.js 的 ziThemeApply() 会临时挂 .zi-theme-switching（80ms 后移除）。
