/* ============================================================
 * wb-modal.css — 通用自定义弹窗（替换浏览器原生 alert/confirm/prompt）
 *
 * 暴露 3 个 JS 函数（详见 wb-modal.js）：
 *   wbConfirm({ title, text, okText, cancelText, danger }) -> Promise<bool>
 *   wbAlert(title, text)                                    -> Promise<void>
 *   wbPrompt({ title, text, defaultValue, okText, cancelText }) -> Promise<string|null>
 *
 * 与页面其他 CSS 完全独立，只要 <link> 这一个文件 + <script src> wb-modal.js
 * 即可在任意 HTML 中使用，无需打包工具。
