## Final Status

**Status:** ✅ **DONE**

**Recommendation:** Ready for merge to master

**Confidence Level:** High

All acceptance criteria met. The chat widget redesign is complete and production-ready.

## WhatsApp / Email 动态配置（2026-06-18）

- [ ] **默认值（未传属性）**：组件（widget-test.html 去掉 data 属性时）与独立页（chat.html 去掉 data 属性时）的 WhatsApp / Email 按钮分别指向 `https://wa.me/+8619037179250` 与 `mailto:info@borderlesscar.com`，与历史行为一致。
- [ ] **自定义值**：widget-test.html 传 `data-whatsapp` / `data-email` 后，组件内三处链接（面板 help-block 的 WhatsApp、面板 help-block 的 Email、邀请卡 WhatsApp、邀请卡 Email）均指向自定义地址。
- [ ] **独立页自定义值**：chat.html 传 `data-whatsapp` / `data-email` 后，两个按钮指向自定义地址。
- [ ] **空字符串**：`data-whatsapp=""` 等价于未传，回退默认值。
- [ ] **JS 未执行**：chat.html 在 JS 禁用 / 未执行时，静态 `href` 仍为默认值，不出现空链接。

## 邀请卡自动弹出开关 + 移动端悬浮按钮（2026-06-23）

### data-auto-invite
- [ ] **默认（未传）**：组件邀请卡在 ~5s（2026-09-04 由 1.8s 调整）后自动弹出，与历史一致。
- [ ] **`data-auto-invite="false"`**：邀请卡不再自动弹出；悬浮按钮照常显示，点击仍能打开聊天面板。
- [ ] **关闭后面板仍可交互**：`data-auto-invite="false"` 时打开聊天面板，输入框可聚焦/打字、发送按钮可点、快捷话题按钮可点（曾因未折叠的邀请卡容器占据空间遮挡面板而全部失效，已修复）。
- [ ] **空值/非法值**：`data-auto-invite=""` 或 `data-auto-invite="0"` 等价于未传，仍自动弹。
- [ ] **与 data-mobile 独立**：`data-mobile="true" data-auto-invite="false"` 时竖排按钮 + 不弹邀请卡，互不影响。

### data-mobile
- [ ] **默认（未传）**：悬浮按钮为桌面款宽药丸（`toggle-btn`，不含 `mobile`），与历史一致。
- [ ] **`data-mobile="true"`**：悬浮按钮为 D2 竖排（`toggle-btn mobile`，含 `.mobile-circle` + `.mobile-label`="Chat with us"），点击圆钮或文字均能开关聊天面板。
- [ ] **移动端位置贴角**：`data-mobile="true"` + `data-position="bottom-right"` 时容器 `bottom/right` 为 `20px`/`16px`（非桌面 `80px`）。
- [ ] **位置覆盖各角**：`data-mobile="true"` 配合 `data-position` 取 `bottom-left`/`top-right`/`top-left`，按钮出现在对应角、贴角、无 JS 报错。
- [ ] **空值/非法值**：`data-mobile=""` 或 `data-mobile="yes"` 等价于未传，回退桌面款。
- [ ] **打开面板不压住按钮**：`data-mobile="true"` + 手机宽度（≤450px）下打开聊天面板，面板底边在 D2 按钮上方、留有 ~12px 间隙、不重叠（曾出现 12px 重叠，已修复）。

## 邀请卡隐形占位修复（2026-09-01）

背景：点 X / No Thanks 写入 `permanent` 后刷新，`startInviteTimer` 在 storage 守卫早退，`showInvite` 永不执行 ⇒ `invitePanel` 恒为 null ⇒ `hideInvite` 提前返回 ⇒ 隐形 `invite-panel`（display:block + opacity:0）在 z-index:99998 容器里拦截右下角点击。修复 = 面板出厂即 `hide` + `.invite-container` 加 `pointer-events:none` + `showInvite` 回流保动画（静态守卫：`tests/test_invite_static.py`）。

- [ ] **permanent 关闭后刷新零遮挡（本 bug）**：等待邀请卡弹出 → 点 X（或 No Thanks）→ 刷新页面 → 卡片不再弹出，**且原卡片区域（右下角 ~360×230px）下方的页面内容可正常点击/悬停**，DevTools 中 `.invite-panel` 带 `hide` 类。
- [ ] **`elementFromPoint` 不命中容器**：上述刷新状态下，Console 对死角区域执行 `document.elementFromPoint(x, y)`，返回页面元素而非 `.invite-container`。
- [ ] **入场动画保留**：正常首访（或清掉 sessionStorage 后刷新），5s 后卡片以 0.3s 淡入+上滑动画出现（非瞬间出现）。
- [ ] **auto-open 面板输入区可交互**：`data-auto-open="true"` 时面板初始即开，输入框可打字、发送/快捷话题按钮可点（此前被隐形邀请卡盒子遮挡）。
- [ ] **首访 5s 窗口零遮挡**：正常首访的前 5s 内（卡片未弹出时），右下角页面内容可点击。
- [ ] **卡片交互不受容器穿透影响**：卡片弹出后，WhatsApp/Email 链接、话题按钮、Start Chat、X、No Thanks 全部可点（`pointer-events` 由 `.invite-panel.show` 的 `auto` 恢复）。
- [ ] **既有邀请卡行为不回归**：本节上方 2026-06-23 的 `data-auto-invite` 五项用例重跑通过。
