 - [x] 全站 dogfood 问题修复（2026-07-25）：修复列表详情页导航、CMS 登录状态、服务详情页软 404 等 High 优先级问题；其中软 404 根因定位为 `(marketing)/loading.tsx` 形成的 Loading/Suspense 边界吞掉了动态路由 `notFound()` 抛出的 NEXT_NOT_FOUND 错误，导致未知 slug 返回 HTTP 200，已移除该 loading.tsx 并修复根 `not-found.tsx`；type-check / lint（0 errors，172 既有 warnings）/ test:unit（72 suites / 954 tests）/ 功能 E2E 140 条全部通过
 - [x] dogfood 剩余问题验证与视觉基线更新（2026-07-26）：浏览器实测确认主导航「产品/解决方案」下拉菜单 click/hover 均可正常展开，问题已随 `(marketing)/loading.tsx` 移除解决；同步修正 `e2e/nav-dropdown.spec.ts` 中断言文本（`睿新ERP管理系统` → `ERP 管理系统`、`行业方案` → `行业解决方案`）；更新 desktop/tablet/mobile/webkit/firefox 全量视觉回归基线（105 张快照）；type-check / lint（0 errors，172 既有 warnings）/ test:unit（72 suites / 954 tests）/ 下拉菜单 E2E 全部通过
 - [x] 全量回归与 E2E 配置修复（2026-07-27）：修复 `e2e/playwright.config.ts` 中 `storageState` 路径错误（由 `./e2e/storageState.json` 改为基于配置文件目录的绝对路径），该错误导致 firefox/webkit 全量 E2E 运行时无法读取 Cookie 偏好状态而全部失败；将 `e2e/p2-functional-e2e.spec.ts` 中「Footer 导航链接可点击」拆分为隐私政策、服务条款两个独立测试，并改用 `page.evaluate` 直接触发点击，避免 Firefox 中连续全页导航与 Playwright locator 评估的竞态超时；重新执行全量回归：type-check / lint（0 errors，172 既有 warnings）/ test:unit（72 suites / 954 tests）/ E2E 全量（631 passed / 8 skipped / 0 failed，含视觉回归、CMS 工作流）全部通过
+- [x] 联系表单 conversion 去重与首页 Hero 品牌标识补齐（2026-07-27）：移除 `contact-content-v3.tsx` 中冗余的 `trackConversion('contact_form_submission')` 调用，改为 `trackContactForm(..., true)`，避免一次成功提交在 GA4 中被计为两次转化；同步更新 `contact-content-v3.test.tsx` 中断言；在 `home-content-v14.tsx` 首页 Hero 主标题上方增加 Logo + 公司中文名 + NOVALON 英文品牌标识，补齐截图中缺失的品牌信息；更新首页相关 desktop/tablet/mobile 视觉回归基线；type-check / lint（0 errors，172 既有 warnings）/ 相关 unit 测试全部通过
