 - 已新增 `render-blocks/list-stat-spec.ts`，收口卡牌/玩家综合力列表的间隔、数值行画布、文字规格、进度条布局和条宽算法；`list-stat.ts` 改为消费 spec，综合力计算、突破加成和绘制顺序保持不变；`list-stat-spec.spec.ts` 覆盖间隔/画布/文字/进度条规格、文本生成和条宽布局，本地 `/查卡 472` 图片 smoke 输出非空。
 - 已新增 `render-blocks/title-spec.ts`，收口通用标题条的背景偏移、两行文字字号/行高/颜色/字体/坐标；`title.ts` 改为消费 spec，标题底图加载、标题文案和绘制顺序保持不变；`title-spec.spec.ts` 覆盖背景偏移、两行文字布局、绘制参数和坐标，本地 `/查卡 472` 图片 smoke 输出非空。
 - 已新增 `render-blocks/list-rarity-spec.ts`，收口星级列表的文字大小、间距和特训星图使用阈值；`list-rarity.ts` 改为消费 spec，星图资源加载、星级数量和列表绘制顺序保持不变；`list-rarity-spec.spec.ts` 覆盖列表规格和 3/4/5 星及未特训边界，本地 `/查卡 472` 图片 smoke 输出非空。
+- 已批量新增 `render-blocks/skill-text-spec.ts`、`list-entity-spec.ts`、`degree-list-spec.ts`、`data-block-spec.ts`、`list-player-ranking-spec.ts`、`list-time-spec.ts`、`timeline-chart-spec.ts`、`cutoff-chart-spec.ts`、`gacha-list-spec.ts`，收口技能角标、基础实体列表、称号/活动奖励称号、数据块、玩家排名行、时间格式、时间线/档线图表和卡池列表文案/布局规格；`skill-text.ts`、`list-attribute.ts`、`list-band.ts`、`list-character.ts`、`degree-badge.ts`、`list-degree-list.ts`、`data-block.ts`、`list-player-ranking.ts`、`list-time.ts`、`timeline-chart.ts`、`cutoff-chart.ts`、`list-gacha-payment-method.ts`、`list-gacha-pick-up.ts`、`list-gacha-rate.ts` 已改为消费 spec；同步修复 `list-band.ts` 多乐队分支误用 `this.hasIcon` 导致图标判断失效的问题；新增对应 8 组 spec 单测，本地 `/查卡 472`、`/查卡池 259`、`/查活动 50`、`/ycx 100 50 cn`、`/查谱面 136 expert` 图片 smoke 输出非空。
+- 已补充 `song-chart-preview-spec.ts` 的封面信息块偏移、ID/难度面板、轨道渐变和双押线高度规格，`song-chart-preview.ts` 不再在绘制函数中散落这些视觉常量；`song-chart-preview-spec.spec.ts` 覆盖新增规格，本地 `/查谱面 136 expert` 图片 smoke 输出非空。
 - smoke/Jenkins/远程调试卡点继续按已固化规则处理：同一卡点第二次尝试前必须改变可验证变量；Jenkins 查询 URL 含方括号时用 `curl -g` 或改查 Jenkins home；线上图片 smoke 必须查询 `commandId`、拉回图片、展示图片、查日志并清理本轮临时目录；PowerShell 双引号 here-string 中不要写 JS `${...}` 模板字面量，避免被 PowerShell 提前插值；smoke 没有真实图片落盘时必须失败。
