L11 · 趋势谱系图
事件序列生命史（首发/重做/休眠/存活）的 Lupi Editorial 真实参考实现。示例结论为“功能兴起、沉寂，再度归来”，副标题已经把图例、单位或时间口径写在图旁：● 已发布 · ○ 已重做 · 虚线代表沉寂年份 · 延伸至今的实线表示仍然存续

实现与使用边界
- 页面直接复用 gallery 中 “Features rise, fall, come back” 的卡片结构和同名渲染块，没有按截图重新绘制。
- 标题、副标题、图形、来源行四件套保持原样；数据编码、比例关系、灰阶和动画节奏由原实现决定。
- 使用时只替换数据与文案，并保持“事件序列生命史（首发/重做/休眠/存活）”这一数据契约；若数据本体改变，应回到总目录重新选型。
- 颜色限于 Mono 灰阶，面积编码继续使用平方根换算；柱长、位置与角度编码不得断轴或视觉夸大。
模板来源：Lieflat Charts
L11 Trend Lineage，真实骨架取自templates/lupi-gallery.html的 “Features rise, fall, come back” 卡片与对应渲染块。
