%% ====== 时序图 1：回复建议区交互流程 ======

    autonumber
    participant User as 坐席
    participant ChatArea as ChatArea
    participant RSA as ReplySuggestArea
    participant ARB as AiRecommendBar
    participant QRB as QuickReplyBar
    participant CS as ConversationStore
    participant RB as ReplyBox
    participant API as Wingman API

    Note over User, API: 场景：坐席选中会话 → 查看 AI 推荐 → 采纳填入输入框 → 发送

    User->>ChatArea: 选中会话
    ChatArea->>CS: selectConversation(id)
    CS->>API: generateDraft(convId)
    API-->>CS: DraftResult {content, confidence, reasoning}
    CS->>CS: aiDrafts.set(convId, draft)
    CS-->>ChatArea: currentConversationId 更新

    ChatArea->>RSA: render (conversationId)
    RSA->>ARB: :recommendations = loadFromStore()
    ARB->>CS: 读取 aiDrafts.get(convId)
    CS-->>ARB: Set~DraftResult~
    ARB-->>User: 横向展示 1-3 条 AI 推荐卡片

    Note over User, ARB: 坐席点击某条推荐

    User->>ARB: 点击推荐卡片 #1
    ARB->>CS: pendingReplyText = recommendation.content
    ARB->>RSA: emit('select', content)
    RSA->>ChatArea: emit('select', content)

    Note over CS, RB: pendingReplyText 变化触发 ReplyBox watch

    CS-->>RB: watch(pendingReplyText) 触发
    RB->>RB: inputText = pendingReplyText
    RB->>RB: pendingReplyText = '' (清空)
    RB-->>User: 输入框显示推荐内容，光标聚焦

    Note over User, RB: 坐席可编辑后发送

    User->>RB: 按 Enter 发送
    RB->>RB: handleSend()
    RB->>ChatArea: emit('send', content)
    ChatArea->>CS: sendReply(content, replyToId?)
    CS->>API: sendMessage(convId, content)
    API-->>CS: Message 对象
    CS-->>ChatArea: messages.push(newMsg)
    ChatArea-->>User: 消息列表刷新，显示新消息

    Note over User, QRB: 场景：坐席使用快速回复

    User->>QRB: 点击 L1 分类 chip（如"账号"）
    QRB->>QRB: navState.l1Index = index
    QRB-->>User: 横向展示 L2 条目预览
    User->>QRB: 点击条目"密码重置指引"
    QRB->>CS: pendingReplyText = template.content
    CS-->>RB: watch 触发，填入输入框
    RB-->>User: 输入框显示快速回复内容


%% ====== 时序图 2：右栏模式切换流程 ======
sequenceDiagram
    autonumber
    participant User as 坐席
    participant PMT as PanelModeToggle
    participant AAP as AiAssistantPanel
    participant WS as Workspace
    participant CS as ConversationStore
    participant DOM as DOM/CSS

    Note over User, DOM: 场景：坐席点击右栏放大/缩小开关

    User->>PMT: 点击开关按钮
    PMT->>AAP: emit('toggle')
    AAP->>WS: emit('toggle')

    alt 当前为 normal 模式 (260px)
        WS->>CS: setPanelMode('expanded')
        CS-->>WS: panelMode = 'expanded'
        WS->>WS: rightSidebarRef.style.width = 'var(--assistant-panel-expanded)'
        WS->>DOM: CSS transition: width 260px → 560px (0.3s)
        DOM-->>User: 右栏平滑放大到 560px
        Note over WS, DOM: 中栏 flex:1 自动缩小，min-width: 400px 保底
    else 当前为 expanded 模式 (560px)
        WS->>CS: setPanelMode('normal')
        CS-->>WS: panelMode = 'normal'
        WS->>WS: rightSidebarRef.style.width = 'var(--assistant-panel-width)'
        WS->>DOM: CSS transition: width 560px → 260px (0.3s)
        DOM-->>User: 右栏平滑缩小到 260px
        Note over WS, DOM: 中栏 flex:1 自动扩大
    end

    Note over User, DOM: 拖拽手柄在放大模式下仍然可用
    Note over WS, DOM: 拖拽范围：200px ~ 560px（上限已调整）
