   「治愈星球」小游戏板块样式（独立命名空间：pm-game-*）
   ---------------------------------------------------------------------
   约定：
     - 全部选择器以 .pm-game-* 前缀命名，不修改 site.css 中的任何规则；
     - 颜色沿用站点主色系（#2f7d6e），只在 body.pm-game-body 作用域内覆盖变量，
       因此对其它页面零影响；
     - 图形的「可爱感」由 CSS 完成：圆角、柔和阴影、渐变光环；
     - 尊重 prefers-reduced-motion：末尾统一降级动画。

/* ==================== 大型欢迎广告位（站长 2026-10-17 需求 2）==================== */
/*
 * 站长二次反馈：「压缩一下大小，做成平齐，不用单独放，要平齐。」
 *
 * 【为什么不再是一个独立 section】
 *   第一版把广告位放在 hero 下面的独立区块里，但 hero 左栏本来就比右栏矮，
 *   于是"空着的地方还是空的，另外又占了一块"。
 *   现在它直接放在 **hero 左栏文案之后**：
 *     · 不新增 section、不加左右外边距 → 宽度与左栏文案完全一致；
 *     · 顶部靠 align-items:start 对齐，底部靠内容撑满 → 上下都齐；
 *     · 视觉上它就是 hero 的一部分，而不是"又一块"。
 * 【体积】900×322 / 160 色 / 约 65KB（原 272KB，压掉 76%）。

 * 站长要求「做成平齐」。顶部已经平齐（align-items:start），
 * 但右栏「宠物乐园」内容更长，底部比左栏多出约 100px。
 * 因此①把右栏内边距与行距略微收紧；②左栏广告位底部对齐。
 * 只动间距、不动字号与内容，视觉密度不变但两栏等高。

/* ==================== 吉祥物文字框：预留高度，彻底消除抖动 ====================
 * 站长 2026-10-17：「ai在阅读和显现文字时，上下两个框会严重抖动，
 *   造成视觉感很糟糕，修改为文字静默展示，不要上下屏幕剧烈抖动。」
 *
 * JS 侧已改为**整句替换**（不再逐字累积）；
 * CSS 侧再给文字框**预留固定高度**：
 *   · min-height 按"最长那句在窄屏下的行数"估算，保证高度恒定；
 *   · overflow 不做滚动（内容一定放得下），只是防极端换行溢出；
 *   · 加 contain: layout 让内部文字变化**不触发外部重排**，
 *     这是消除抖动的关键 —— 浏览器知道这块的高度只由自己决定。
 * 双保险后：无论文案多长、切到第几句，容器高度都纹丝不动。

/* ==================== 广告位下方文字区收紧（站长 2026-10-17 第二次反馈）====================
 * 站长指着下方文字框：「下方短箭头框文字向上调一点，下方挡住了」。
 * 原因：之前为避免抖动把 .pm-hero-banner__text 的 min-height 设成了 4.1em，
 * 而文案本身只有两行，于是多出来的空档把按钮条往下挤，
 * 视觉上像"文字被下面的边框挡住"。
 * 现在：文字框按**实际两行**预留（2.8em），并整体上移一点点，
 * 既保持"高度恒定不抖动"，又不留多余空白。

/* ==================== 文字框高度必须"容纳最长一句" ====================
 * 实测残存 8.1px 抖动：把预留高度压到 2.8em 后，
 * 短句占 2 行、最长句占 3 行 → 高度仍在变。
 * 结论：**预留高度必须 ≥ 最长一句所需行数**，否则省下的空白会换回抖动。
 * 这里按"广告位文案最长句在 670px 宽度下需要 3 行"预留（约 4.15em）。

/* ==================== 消除左栏留白，同时保持底边对齐（站长 2026-10-17）====================
 * 【实测问题】按钮行底 y609、广告位顶 y661 → **中间空出 52px**。
 * 【根因】广告位为了"贴住右栏底边"用了 margin-top:auto，
 *   于是左栏内容比右栏短多少，这块空白就堆在按钮与广告位之间。
 * 【修法】不让"空白"堆在两段之间，而是**让广告位图片自己长高**去补齐：
 *   · 广告位去掉 margin-top，紧跟按钮（间距 = 正常 16px）；
 *   · 广告位容器改 flex 纵向，图片 flex:1 + object-fit:cover
 *     → 图片按可用高度自动放大，多出来的高度被图片吃掉，而不是留成空白；
 *   · object-position 靠上/居中，保证吉祥物与文字不被裁掉重点。
 * 这样"贴到底"与"没有留白"同时成立。
