+# Mini Program Life Event Detail Actions Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** 调整小程序人生轨迹详情页，把事件标题卡与事件描述卡合并，移除顶部悬浮操作 icon，并将收藏、分享、分析、编辑、收起和“聊聊”入口按新布局展示。
+
+**Architecture:** 只修改 `mini-program/src/pages/life-event/detail.vue`。模板层用新的 `event-content-card` 替换 `floating-nav`、`hero-card`、`description-card` 组合；脚本层增加 `scrollTop`、`currentScrollTop`、`onContentScroll` 与 `scrollToAnalysis` 来支持分析按钮定位；样式层复用当前宇宙玻璃风格并新增局部按钮和 Markdown 折叠样式。
+
+**Tech Stack:** UniApp, Vue 3 `<script setup>`, CSS scoped, existing `mini-program/src/components/Markdown.vue`, npm scripts from `mini-program/package.json`.
+
+---
+
+## File Structure
+
+- Modify: `mini-program/src/pages/life-event/detail.vue`
+  - Template: 合并事件标题区和事件描述区，迁移操作按钮，底部只保留居中的聊天主按钮。
+  - Script: 删除 `useMenuButtonSafeArea` 使用，新增 `scrollTop`、`currentScrollTop`、`onContentScroll`、`scrollToAnalysis`，保留现有业务方法。
+  - Style: 删除顶部悬浮导航样式，新增合并卡、正文 Markdown 折叠、内容区按钮和底部聊天按钮样式。
+
+- Verify only: `mini-program/src/components/Markdown.vue`
+  - 不改文件，仅复用 `<Markdown :content="eventDescription" />`。
+
+---
+
+### Task 1: Template Restructure
+
+**Files:**
+- Modify: `mini-program/src/pages/life-event/detail.vue`
+
+- [ ] **Step 1: Remove the floating nav block**
+
+Delete this block from the template:
+
+```vue
+<view class="floating-nav" :style="floatingTopStyle">
+  <view class="circle-btn" @click="goBack">
+    <view class="back-icon"></view>
+  </view>
+  <view class="circle-btn" @click="openMore">
+    <view class="more-dot"></view>
+    <view class="more-dot"></view>
+    <view class="more-dot"></view>
+  </view>
+</view>
+```
+
+Expected result: 页面左上角和右上角不再渲染悬浮 icon。
+
+- [ ] **Step 2: Add scroll state binding to the page scroll-view**
+
+Change the current scroll-view opening tag from:
+
+```vue
+<scroll-view class="content" scroll-y :show-scrollbar="false">
+```
+
+to:
+
+```vue
+<scroll-view
+  class="content"
+  scroll-y
+  :show-scrollbar="false"
+  :scroll-top="scrollTop"
+  @scroll="onContentScroll"
+  scroll-with-animation
+>
+```
+
+Expected result: `scrollToAnalysis` can move the scroll-view to the AI 分析 section and account for the current scroll position.
+
+- [ ] **Step 3: Replace hero-card and description-card with the merged event-content-card**
+
+Replace the whole existing `hero-card` and `description-card` blocks with:
+
+```vue
+<view class="event-content-card glass-card">
+  <view class="event-hero-section">
+    <view class="hero-timeline">
+      <view class="timeline-glow"></view>
+      <view class="timeline-node"></view>
+      <view class="timeline-line"></view>
+    </view>
+
+    <view class="hero-copy">
+      <text class="year">{{ eventYear }}</text>
+      <view class="date-row">
+        <text class="date-range">{{ dateRange }}</text>
+        <text class="type-chip">{{ primaryTag }}</text>
+      </view>
+      <text class="event-title">{{ displayEvent.title || '决定全职做自己热爱的AI产品' }}</text>
+      <view class="location-row">
+        <view class="pin-icon"></view>
+        <text>{{ locationText }}</text>
+      </view>
+    </view>
+
+    <view class="memory-cover">
+      <view class="cover-sky"></view>
+      <view class="cover-window"></view>
+      <view class="cover-desk"></view>
+      <view class="cover-screen main"></view>
+      <view class="cover-screen small left"></view>
+      <view class="cover-screen small right"></view>
+    </view>
+    <view class="hero-star">★</view>
+  </view>
+
+  <view class="event-body-section">
+    <view class="event-body-toolbar">
+      <view class="content-action favorite-action" @click="toggleFavorite">
+        <view class="bookmark-icon" :class="{ active: isFavorite }"></view>
+        <text>{{ isFavorite ? '已收藏' : '收藏' }}</text>
+      </view>
+
+      <view class="toolbar-right">
+        <view class="analysis-pill" @click="scrollToAnalysis">
+          <text>分析</text>
+        </view>
+        <view class="content-action share-action" @click="shareCurrent">
+          <view class="share-icon">
+            <view></view>
+            <view></view>
+            <view></view>
+          </view>
+          <text>分享</text>
+        </view>
+      </view>
+    </view>
+
+    <view class="section-title-row description-title-row">
+      <view class="orbit-icon"></view>
+      <text>事件描述</text>
+    </view>
+
+    <view class="description-markdown" :class="{ collapsed: isDescriptionCollapsed }">
+      <Markdown :content="eventDescription" />
+    </view>
+
+    <view class="event-body-footer">
+      <view class="content-action edit-action" @click="editEvent">
+        <view class="edit-icon"></view>
+        <text>编辑</text>
+      </view>
+      <text class="collapse-action" @click="isDescriptionCollapsed = !isDescriptionCollapsed">
+        {{ isDescriptionCollapsed ? '展开' : '收起' }} ^
+      </text>
+    </view>
+  </view>
+</view>
+```
+
+Expected result: 事件信息和事件描述在同一张卡内，正文通过 `Markdown` 组件渲染。
+
+- [ ] **Step 4: Add the analysis anchor data attribute**
+
+Change the current AI analysis opening block from:
+
+```vue
+<view class="analysis-panel">
+```
+
+to:
+
+```vue
+<view class="analysis-panel" id="analysisPanel">
+```
+
+Expected result: `uni.createSelectorQuery()` can locate the AI 分析 block.
+
+- [ ] **Step 5: Replace bottom action bar with centered chat action**
+
+Replace the existing bottom action bar:
+
+```vue
+<view class="bottom-actions" :style="{ paddingBottom: bottomInset + 'px' }">
+  <view class="bottom-action" @click="editEvent">
+    <view class="edit-icon"></view>
+    <text>编辑</text>
+  </view>
+  <view class="bottom-action" @click="toggleFavorite">
+    <view class="bookmark-icon" :class="{ active: isFavorite }"></view>
+    <text>{{ isFavorite ? '已收藏' : '收藏' }}</text>
+  </view>
+  <view class="chat-action" @click="chatEvent">
+    <view class="chat-badge">AI</view>
+    <text>和开开聊聊这段经历</text>
+  </view>
+  <view class="bottom-action" @click="shareCurrent">
+    <view class="share-icon">
+      <view></view>
+      <view></view>
+      <view></view>
+    </view>
+    <text>分享</text>
+  </view>
+</view>
+```
+
+with:
+
+```vue
+<view class="bottom-actions" :style="{ paddingBottom: bottomInset + 'px' }">
+  <view class="chat-action" @click="chatEvent">
+    <view class="chat-badge">AI</view>
+    <text>聊聊</text>
+  </view>
+</view>
+```
+
+Expected result: 底部只保留居中的紫色主按钮，文案为“聊聊”。
+

+
+### Task 2: Script State And Methods
+
+**Files:**
+- Modify: `mini-program/src/pages/life-event/detail.vue`
+
+- [ ] **Step 1: Remove the unused safe-area composable import**
+
+Change imports from:
+
+```js
+import { computed, onMounted, onUnmounted, ref } from 'vue'
+import { useAppStore } from '../../stores/app.js'
+import Markdown from '../../components/Markdown.vue'
+import { useMenuButtonSafeArea } from '../../composables/useMenuButtonSafeArea.js'
+import analytics from '../../services/analytics.js'
+```
+
+to:
+
+```js
+import { computed, onMounted, onUnmounted, ref } from 'vue'
+import { useAppStore } from '../../stores/app.js'
+import Markdown from '../../components/Markdown.vue'
+import analytics from '../../services/analytics.js'
+```
+
+Expected result: 没有未使用的 `useMenuButtonSafeArea` import。
+
+- [ ] **Step 2: Replace floating nav state with scroll state**
+
+Change:
+
+```js
+const store = useAppStore()
+const pagePath = '/pages/life-event/detail'
+const { floatingTopStyle } = useMenuButtonSafeArea()
+const safeAreaBottom = ref(0)
+const eventId = ref('')
+const cachedEvent = ref(null)
+const isFavorite = ref(false)
+const isDescriptionCollapsed = ref(false)
+```
+
+to:
+
+```js
+const store = useAppStore()
+const pagePath = '/pages/life-event/detail'
+const safeAreaBottom = ref(0)
+const eventId = ref('')
+const cachedEvent = ref(null)
+const isFavorite = ref(false)
+const isDescriptionCollapsed = ref(false)
+const scrollTop = ref(0)
+const currentScrollTop = ref(0)
+```
+
+Expected result: scroll-view has a reactive value available for animated positioning.
+
+- [ ] **Step 3: Add scroll methods before editEvent**
+
+Insert these methods before `const editEvent = () => {`:
+
+```js
+const onContentScroll = (event) => {
+  currentScrollTop.value = event.detail?.scrollTop || 0
+}
+
+const scrollToAnalysis = () => {
+  uni.createSelectorQuery()
+    .select('#analysisPanel')
+    .boundingClientRect((rect) => {
+      if (!rect) return
+      scrollTop.value = Math.max(0, currentScrollTop.value + rect.top - 24)
+    })
+    .exec()
+}
+```
+
+Expected result: 点击“分析”后 scroll-view 会向 AI 分析卡移动。
+
+- [ ] **Step 4: Keep existing business methods unchanged**
+
+Do not change the bodies of these existing methods:
+
+```js
+const editEvent = () => {
+  if (!eventId.value) return
+  uni.navigateTo({ url: `/pages/life-event/form?id=${eventId.value}` })
+}
+
+const toggleFavorite = async () => {
+  if (!eventId.value) return
+  const next = !isFavorite.value
+  const result = await store.favoriteEvent({ id: eventId.value, favorite: next })
+  if (!result.success) {
+    uni.showToast({ title: result.error || '收藏失败', icon: 'none' })
+    return
+  }
+  isFavorite.value = next
+  if (next) uni.setStorageSync(`event_favorite_${eventId.value}`, '1')
+  else uni.removeStorageSync(`event_favorite_${eventId.value}`)
+  analytics.track('life_event_favorite', {
+    life_event_id: eventId.value,
+    favorite: next
+  }, { eventType: 'life_event', pagePath })
+  uni.showToast({ title: next ? '已收藏' : '已取消收藏', icon: 'success' })
+}
+
+const chatEvent = async () => {
+  const result = await store.chatAboutEvent({
+    id: eventId.value,
+    title: displayEvent.value.title,
+    content: displayEvent.value.content
+  })
+  uni.showModal({
+    title: '和开开聊聊',
+    content: result.success ? result.data?.reply || '聊天能力已准备' : result.error || '聊天服务暂不可用',
+    showCancel: false
+  })
+}
+
+const shareCurrent = async () => {
+  const result = await store.shareEvent({
+    id: eventId.value,
+    title: displayEvent.value.title,
+    content: displayEvent.value.content
+  })
+  if (!result.success) {
+    uni.showToast({ title: result.error || '分享失败', icon: 'none' })
+    return
+  }
+  analytics.track('life_event_share', {
+    life_event_id: eventId.value,
+    tag_count: Array.isArray(displayEvent.value.tags) ? displayEvent.value.tags.length : 0
+  }, { eventType: 'life_event', pagePath })
+  uni.setClipboardData({
+    data: result.data?.shareText || `分享我的人生轨迹：${displayEvent.value.title || ''}`,
+    success: () => uni.showToast({ title: '分享文案已复制', icon: 'success' })
+  })
+}
+```
+
+Expected result: 编辑、收藏、分享、聊天功能沿用现有行为。
+

+
+### Task 3: Styles For Merged Card And Actions
+
+**Files:**
+- Modify: `mini-program/src/pages/life-event/detail.vue`
+
+- [ ] **Step 1: Update z-index selector**
+
+Change:
+
+```css
+.floating-nav,
+.content,
+.bottom-actions {
+  position: relative;
+  z-index: 1;
+}
+```
+
+to:
+
+```css
+.content,
+.bottom-actions {
+  position: relative;
+  z-index: 1;
+}
+```
+
+Expected result: CSS no longer references removed `floating-nav`.
+
+- [ ] **Step 2: Delete removed floating navigation styles**
+
+Delete these style blocks:
+
+```css
+.floating-nav {
+  height: 108rpx;
+  flex-shrink: 0;
+  display: flex;
+  align-items: center;
+  justify-content: space-between;
+  padding: 0 32rpx;
+  box-sizing: border-box;
+}
+
+.circle-btn {
+  width: 64rpx;
+  height: 64rpx;
+  border-radius: 50%;
+  display: flex;
+  align-items: center;
+  justify-content: center;
+  gap: 5rpx;
+  color: #fff;
+  border: 1rpx solid rgba(118, 82, 225, 0.35);
+  background: rgba(22, 18, 63, 0.72);
+  box-shadow: inset 0 0 20rpx rgba(137, 91, 255, 0.1);
+}
+
+.back-icon {
+  width: 23rpx;
+  height: 23rpx;
+  border-left: 6rpx solid #fff;
+  border-bottom: 6rpx solid #fff;
+  transform: rotate(45deg);
+  margin-left: 7rpx;
+}
+
+.more-dot {
+  width: 7rpx;
+  height: 7rpx;
+  border-radius: 50%;
+  background: #fff;
+}
+```
+
+Expected result: no dead CSS for removed top icons.
+
+- [ ] **Step 3: Adjust scroll content spacing**
+
+Change:
+
+```css
+.content {
+  flex: 1;
+  height: 0;
+  min-height: 0;
+  box-sizing: border-box;
+  padding: 0 32rpx 134rpx;
+}
+```
+
+to:
+
+```css
+.content {
+  flex: 1;
+  height: 0;
+  min-height: 0;
+  box-sizing: border-box;
+  padding: 36rpx 32rpx 154rpx;
+}
+```
+
+Expected result: merged card starts with breathing room after top safe area removal, and bottom content is not covered by the chat button.
+
+- [ ] **Step 4: Replace hero-card styles with event-content-card and event-hero-section**
+
+Replace:
+
+```css
+.hero-card {
+  position: relative;
+  min-height: 264rpx;
+  border-radius: 28rpx;
+  display: grid;
+  grid-template-columns: 70rpx 1fr 148rpx;
+  gap: 20rpx;
+  padding: 38rpx 34rpx 32rpx;
+  box-sizing: border-box;
+}
+```
+
+with:
+
+```css
+.event-content-card {
+  position: relative;
+  overflow: hidden;
+  border-radius: 30rpx;
+}
+
+.event-hero-section {
+  position: relative;
+  min-height: 264rpx;
+  display: grid;
+  grid-template-columns: 70rpx 1fr 148rpx;
+  gap: 20rpx;
+  padding: 40rpx 34rpx 34rpx;
+  box-sizing: border-box;
+  background:
+    radial-gradient(circle at 86% 12%, rgba(129, 76, 255, 0.22), transparent 36%),
+    linear-gradient(145deg, rgba(6, 8, 35, 0.98) 0%, rgba(15, 13, 58, 0.96) 58%, rgba(23, 16, 72, 0.92) 100%);
+  box-shadow: inset 0 -1rpx 0 rgba(164, 116, 255, 0.22), inset 0 0 42rpx rgba(63, 45, 148, 0.16);
+}
+```
+
+Expected result: top half of the merged card is visually deeper than the body area.
+
+- [ ] **Step 5: Replace description-card styles with event body styles**
+
+Replace:
+
+```css
+.description-card,
+.tags-card {
+  border-radius: 28rpx;
+  margin-top: 18rpx;
+  padding: 28rpx 30rpx;
+  box-sizing: border-box;
+}
+```
+
+with:
+
+```css
+.event-body-section {
+  position: relative;
+  padding: 26rpx 30rpx 24rpx;
+  box-sizing: border-box;
+  background:
+    radial-gradient(circle at 92% 0%, rgba(159, 98, 255, 0.12), transparent 36%),
+    rgba(13, 16, 52, 0.62);
+}
+
+.tags-card {
+  border-radius: 28rpx;
+  margin-top: 18rpx;
+  padding: 28rpx 30rpx;
+  box-sizing: border-box;
+}
+```
+
+Expected result: description body sits inside the merged card and related tags keep their card styling.
+
+- [ ] **Step 6: Add content action toolbar styles before `.section-title-row`**
+
+Insert:
+
+```css
+.event-body-toolbar,
+.event-body-footer {
+  display: flex;
+  align-items: center;
+  justify-content: space-between;
+  gap: 18rpx;
+}
+
+.event-body-toolbar {
+  min-height: 64rpx;
+}
+
+.toolbar-right {
+  display: flex;
+  align-items: center;
+  gap: 14rpx;
+}
+
+.content-action {
+  min-height: 64rpx;
+  display: flex;
+  align-items: center;
+  justify-content: center;
+  gap: 10rpx;
+  color: rgba(238, 231, 255, 0.88);
+  font-size: 23rpx;
+  font-weight: 800;
+}
+
+.favorite-action,
+.share-action,
+.edit-action {
+  padding: 0 4rpx;
+}
+
+.analysis-pill {
+  min-width: 92rpx;
+  height: 54rpx;
+  padding: 0 24rpx;
+  box-sizing: border-box;
+  border-radius: 0 18rpx 18rpx 18rpx;
+  display: flex;
+  align-items: center;
+  justify-content: center;
+  color: rgba(231, 217, 255, 0.86);
+  font-size: 23rpx;
+  font-weight: 900;
+  background: rgba(157, 104, 255, 0.18);
+  border: 1rpx solid rgba(193, 154, 255, 0.24);
+  box-shadow: inset 0 0 18rpx rgba(185, 124, 255, 0.08);
+}
+
+.description-title-row {
+  margin-top: 16rpx;
+}
+```
+
+Expected result: 收藏与分享同一水平线，分析按钮弱化并位于右上凹位。
+
+- [ ] **Step 7: Replace description text styles with Markdown wrapper styles**
+
+Replace:
+
+```css
+.description-text {
+  display: block;
+  margin-top: 24rpx;
+  color: rgba(227, 218, 246, 0.73);
+  font-size: 25rpx;
+  line-height: 1.75;
+}
+
+.description-text.collapsed {
+  display: -webkit-box;
+  overflow: hidden;
+  -webkit-line-clamp: 3;
+  -webkit-box-orient: vertical;
+}
+
+.collapse-action {
+  display: block;
+  margin-top: 14rpx;
+  text-align: right;
+  color: #a970ff;
+  font-size: 24rpx;
+  font-weight: 800;
+}
+```
+
+with:
+
+```css
+.description-markdown {
+  margin-top: 22rpx;
+  overflow: hidden;
+}
+
+.description-markdown.collapsed {
+  max-height: 168rpx;
+}
+
+.event-body-footer {
+  margin-top: 18rpx;
+}
+
+.collapse-action {
+  min-height: 64rpx;
+  display: flex;
+  align-items: center;
+  justify-content: flex-end;
+  color: #a970ff;
+  font-size: 24rpx;
+  font-weight: 800;
+}
+```
+
+Expected result: Markdown content can collapse without changing `Markdown.vue`.
+
+- [ ] **Step 8: Replace bottom action layout styles**
+
+Replace the current `.bottom-actions`, `.bottom-action`, and `.chat-action` blocks:
+
+```css
+.bottom-actions {
+  position: absolute;
+  left: 0;
+  right: 0;
+  bottom: 0;
+  min-height: 108rpx;
+  box-sizing: border-box;
+  display: grid;
+  grid-template-columns: 0.76fr 0.76fr 2fr 0.76fr;
+  align-items: center;
+  gap: 8rpx;
+  padding: 14rpx 32rpx 0;
+  border-radius: 36rpx 36rpx 0 0;
+  border-top: 1rpx solid rgba(126, 87, 255, 0.32);
+  background: rgba(13, 13, 43, 0.94);
+  box-shadow: 0 -14rpx 44rpx rgba(0, 0, 0, 0.45), inset 0 0 28rpx rgba(143, 92, 255, 0.1);
+  backdrop-filter: blur(28rpx);
+  -webkit-backdrop-filter: blur(28rpx);
+}
+
+.bottom-action,
+.chat-action {
+  height: 72rpx;
+  display: flex;
+  align-items: center;
+  justify-content: center;
+  gap: 10rpx;
+  color: rgba(238, 231, 255, 0.9);
+  font-size: 24rpx;
+  font-weight: 800;
+}
+
+.bottom-action {
+  min-width: 0;
+}

+}
+```
+
+Expected result: “聊聊” button is centered and visually primary.
+
+- [ ] **Step 9: Confirm shared icon styles still work in new locations**
+
+Keep the existing `.edit-icon`, `.bookmark-icon`, `.share-icon`, and `.chat-badge` blocks unchanged.
+
+Expected result: content toolbar and footer reuse the existing drawn icons with no new asset dependency.
+

+
+### Task 4: Build Verification
+
+**Files:**
+- Verify: `mini-program/src/pages/life-event/detail.vue`
+- Verify: `mini-program/package.json`
+
+- [ ] **Step 1: Run H5 production build**
+
+Run:
+
+```bash
+cd mini-program
+npm run build:h5
+```
+
+Expected: command exits with code 0 and Vite/UniApp writes the H5 build output under `mini-program/dist/build/h5` or the configured UniApp output directory.
+
+- [ ] **Step 2: Fix compile errors by editing only detail.vue**
+
+If the build reports a compile error in `detail.vue`, fix the exact syntax issue in `mini-program/src/pages/life-event/detail.vue`, then rerun:
+
+```bash
+cd mini-program
+npm run build:h5
+```
+
+Expected: command exits with code 0.
+
+---
+
+### Task 5: Browser Verification
+
+**Files:**
+- Verify: `mini-program/src/pages/life-event/detail.vue`
+
+- [ ] **Step 1: Start H5 dev server**
+
+Run:
+
+```bash
+cd mini-program
+npm run dev:h5
+```
+
+Expected: dev server prints a local URL, usually `http://localhost:5173`.
+
+- [ ] **Step 2: Open the app in a browser**
+
+Use the available browser automation tool to open:
+
+```text
+http://localhost:5173
+```
+
+Expected: app loads without a blank screen.
+
+- [ ] **Step 3: Navigate to a life event detail page**
+
+Use the app UI to reach 人生轨迹详情页. If the local dev data has no event entry, open a detail URL with the current route format after creating or selecting an event through the UI.
+
+Expected: the detail page renders and uses local store/cached fallback data when available.
+
+- [ ] **Step 4: Verify visual requirements**
+
+Check these exact outcomes:
+
+- The left-top edit icon and right-top more icon are absent.
+- Event title information and event description are inside one merged card.
+- The upper title area is visibly darker than the body area.
+- Event description is rendered through Markdown formatting.
+- 收藏 is at the body area's left top.
+- 分享 is horizontally aligned with 收藏.
+- 分析 is a lighter pill at the right-top side of the body area.
+- 编辑 is at the body area's left bottom.
+- 编辑 and 收起 or 展开 are horizontally aligned.
+- 分析 and 收起 or 展开 are vertically aligned on the right side.
+- The bottom button is centered and displays “聊聊”.
+- The page has no overlapping text at mobile width.
+
+Expected: all checks pass.
+
+- [ ] **Step 5: Verify button behavior and console health**
+
+Click these controls:
+
+- 收藏
+- 分享
+- 分析
+- 编辑
+- 收起 or 展开
+- 聊聊
+
+Expected:
+
+- 收藏 toggles visual state or shows the existing failure toast when unauthenticated.
+- 分享 copies or shows the existing failure toast.
+- 分析 scrolls to the AI 分析 section.
+- 编辑 navigates to the event form when `eventId` exists.
+- 收起/展开 toggles Markdown body height.
+- 聊聊 opens the existing chat modal or shows existing failure text.
+- Browser Console contains no new errors from `detail.vue`.

+## Self-Review
+
+Spec coverage:
+
+- Top icons removed: Task 1 Step 1, Task 3 Step 1-2.
+- Title and content merged: Task 1 Step 3, Task 3 Step 4-5.
+- Darker title area: Task 3 Step 4.
+- Markdown description rendering: Task 1 Step 3, Task 3 Step 7.
+- Button placement: Task 1 Step 3 and Step 5, Task 3 Step 6-8.
+- Existing behavior preserved: Task 2 Step 4.
+- Browser verification required by repository rules: Task 5.
+
+Placeholder scan:
+
+- This plan contains no placeholder or incomplete implementation steps.
+
+Type and property consistency:
+
+- `scrollTop` is declared as `ref(0)` and bound as `:scroll-top="scrollTop"`.
+- `currentScrollTop` is declared as `ref(0)` and updated by `@scroll="onContentScroll"`.
+- `scrollToAnalysis` is referenced by the template and defined in script.
+- `analysisPanel` is the exact id used by selector query.
