 # CHANGELOG
 
+- [2026-09-23 06:30] FEAT: v2.15 图纸封面图一致性收尾——官方 PNG 剩余元素补齐。①分段尺寸标注: 按重放区域分割点生成蓝色分段(每格宽/高)+总尺寸双排标注(端部刻度, 左侧文字旋转), 替换原仅总宽高文本; ②玻璃配置第二行: fl.spet.sp(如 5+12+5)画于编号下方(704 无配置不画, 与官方一致); ③中梃与外框交点白色连接件方块; 修复 spIdx 遍历变量; 验证: 704 画布与官方封面图逐元素一致(分段 663/1137/393/1207+总 1800/1600), ui-shots 6 页无报错 (Files: frontend/src/components/WindoorCanvas.vue, shots/*)
+
 - [2026-09-23 06:05] FEAT: v2.14 2D 图纸样式对齐源站设计图(官方 PNG 逐元素比对)。WindoorCanvas 绘制层重写: ①玻璃 teal 渐变(官方配色)+深色细描边; ②型材立体三段线(深轮廓+紫灰主体+白高光, 宽度=60mm 料宽映射限幅), 外框/中梃/扇料框统一; ③四角白色角码; ④开向符号对齐官方: 平开=虚线大三角(apex 按 hm.openDirection 指铰链侧, wtf 同样画三角), 推拉=水平滑行箭头(成对反向); ⑤把手(铰链对面侧白条)+锁点小方块; ⑥玻璃编号标签(frame/sash 的 mm.fls[].ser.text 经 polyId 树寻址定位到格中心); ⑦尺寸标注改官方蓝色带端部刻度; CombineCanvas 玻璃/型材配色同步; 验证: 设计图纸 704 画布与官方平面图逐元素一致, ui-shots 6 页无报错 (Files: frontend/src/components/WindoorCanvas.vue, frontend/src/components/CombineCanvas.vue, shots/*)
 
 - [2026-09-23 05:40] FEAT: v2.13 细节尺寸编辑——组合与样板的每一格可精确编辑。①WindoorCanvas: 点击玻璃格选中(蓝虚线高亮+格尺寸标注), HUD 输入格W/格H 自动平移该格边界中梃(优先右/下边界其次左/上, 共线同位多段成组移动+组内各段裁剪 bbox 内缩30mm 交集 clamp); 选中中梃可输入距左/上边缘位置精确移动; 中梃拖动改组移动(修复共线多段拖动错位); ②CombineView: 工具栏新增"编辑细节"对话框(复用 WindoorCanvas 编辑器 editable 模式), 保存后原位写回对应单元形状(__uid/__name 保留, rev 驱动 3D 预览重建); ③CombineCanvas: 中梃改按各自裁剪 bbox 绘制(原横梃画满宽的示意画法与真实分格不符); ④TemplatesView 编辑提示文案更新; 验证: 真实浏览器截图(格选中 663×1207→格H=800 横梃精确下移/梃位 900 移动/组合对话框编辑保存写回后主画布与 3D 同步), vue-tsc 0 错误 (Files: frontend/src/components/WindoorCanvas.vue, frontend/src/components/CombineCanvas.vue, frontend/src/views/CombineView.vue, frontend/src/views/TemplatesView.vue, frontend/scripts/verify-detail.mjs, shots/detail-*.png)
