 - **根因**：自定义 tabBar 组件的 `pageLifetimes.show()` 对自定义 tabBar **不触发**（微信框架特殊行为——自定义 tabBar 由框架管理，不走普通组件的页面生命周期）。各 tab 页 `onShow` 里只做了 `tb.setData({selected:X})` 设高亮，没有同步主题；`onSelectDarkMode` 里 `getCurrentPages()` 只返回当前 tab 页（其他 tab 不在页面栈里），所以 `tb.updateTheme()` 只刷新了设置页的 tabBar 实例。
 - **修复**：4 个 tab 页 `onShow` 里获取 tabBar 后，在 `setData({selected:X})` 之后加一行 `tb.updateTheme()`。`updateTheme()` 内部调 `applyThemeToPage(this)`（有"样式未变则跳过"的优化），不会产生多余渲染。涉及 `pages/index/index.js`、`pages/records/records.js`、`pages/leaderboard/leaderboard.js`、`pages/settings/settings.js`。
 - **教训**：自定义 tabBar 不能依赖 `pageLifetimes` 做状态同步，必须在各 tab 页 `onShow` 里显式调 `this.getTabBar()` 更新。

+## 修复：循环训练偶数组数休息语音被「一半」提示吞掉
+- **现象**：循环训练设 2 组时，第 1 组练完进入休息，本该播 `restStart`「休息一下」，实际播的是 `halfway`「已完成一半啦」，休息语音不响。
+- **根因**：偶数 set 数时 `sets×hold/2` 正好落在某组练完→休息切换的那一 tick。`_circuitCue` 先播 halfway 并设 `_voiceBusyUntil=now+2600` 占麦；紧接着 `_advance()`→`_circuitPhase('resting')` 检查麦占用，`restStart` 被静音。原代码注释有意让"进度提示优先于阶段提示"，但偶数组数下两者撞车。
+- **修复**：`_circuitCue` 里先算 `atRestBoundary`(phaseRemaining<=0 && rest>0 && setIndex<sets) 与 `restWillSpeak`(hold>=10 && rest>=5)；halfway/last30/last10 在"落在休息边界且 restStart 会播"时跳过自身，让休息语音优先。奇数组数一半点在中段不会撞车，不动；短组配置 rest 不播也保持原 halfway 行为，无回归。改 `pages/timer/timer.js` 的 `_circuitCue`。
+- 顺带：last30/last10 在更长偶数组数(如 4 组×30s 的 set3→rest)也会撞同一问题，一并按同规则让位，行为一致。
