 * ------------------------------------------------------------
 * Chrome/Edge 的密码管理器与表单自动填充会给输入框套一层默认的
 * 白底黑字（:-webkit-autofill 伪类），在深色 UI 里表现为一条刺眼的
 * 白色长条，与手动输入的观感完全不一致。
 *   ① background/color 的变化被拖成"近乎无限长"的过渡 —— 那层白底
 *      永远来不及显现，等效于保持透明；
 *   ② -webkit-text-fill-color 锁成 currentColor，文字颜色与手动输入一致。
 * 与 console.html 搜索框的 readonly 物理阻止是两层独立防御，互不替代。
