/*
 * 气球射手（BALLOON POP）· 样式
 *
 * 版面只有四层，**整页不滚动**（手机上瞄准时页面跟着动是最难受的）：
 *   顶栏（按钮） / 副栏（心 + 分数） / 瞄准方式一行 / 游戏区（吃掉剩下的全部空间）
 * 画布的尺寸不是 CSS 定的，是 `game.mjs` 的 `layout()` 按可用空间算出来写上去的
 * （玩法坐标固定 360 宽，纵向按屏幕比例拉伸，所以任何手机上都不留黑边）。
 */

/* ① [hidden] 必须压过作者样式 —— 下面的 .scores / .overlay / .title 都写了 display:flex，
      浏览器给 [hidden] 的 display:none 会被盖掉 → 面板一进页面就浮着、点「关闭」没反应。 */
