 * Description        : HX-221C / MST WebUSB DFU 升级工具界面样式（深色工程师风格）
 *                      本文件由 MST/Host/style.css 作用域化而来——所有选择器前缀
 *                      .mst-tool，确保深色主题与变量不会泄漏到站点的浅色主题，
 *                      也不会与站点 Tailwind / 组件类（.btn/.card/.badge 等）冲突。
 *                      若上游 style.css 更新，请重新前缀化同步本文件。
