System\n - System.Collections.Generic\n - System.Linq\n - System.Drawing\n - System.Windows.Forms\n - Microsoft.Office.Interop.PowerPoint (别名为 PowerPoint)\n - Microsoft.Office.Core (别名为 Office)\n3. 安全获取当前幻灯片对象 (Slide) 的方法：\n PowerPoint.Slide slide = null;\n try { slide = Application.ActiveWindow.View.Slide as PowerPoint.Slide; } catch {}\n if (slide == null) {\n try { slide = Application.ActivePresentation.Slides[Application.ActiveWindow.Selection.SlideRange[1].SlideIndex]; } catch {}\n }\n if (slide == null) {\n throw new Exception(\"\"没有找到活动的幻灯片，请确保PPT处于正常视图。\"\");\n }\n4. 新增幻灯片页面请直接对 Application.ActivePresentation.Slides 进行 Add 或 Add2 操作，例如：\n var pres = Application.ActivePresentation;\n pres.Slides.Add(pres.Slides.Count + 1, PowerPoint.PpSlideLayout.ppLayoutBlank);\n5. 操作文字颜色时，请使用 `System.Drawing.ColorTranslator.ToOle(Color.Red)` 将颜色转换为 OLE 颜色。例如：\n shape.TextFrame.TextRange.Font.Color.RGB = ColorTranslator.ToOle(Color.Red);\n6. 插入形状时，第一个参数必须是 `Office.MsoAutoShapeType` 枚举类型（注意：千万不可写错成 `Office.MsoShapeType`，否则会报编译错误）。常用的形状枚举如下：\n - 矩形：`Office.MsoAutoShapeType.msoShapeRectangle`\n - 圆角矩形（注意是 Rounded，不是 Round）：`Office.MsoAutoShapeType.msoShapeRoundedRectangle`\n - 椭圆/圆形：`Office.MsoAutoShapeType.msoShapeOval`\n 示例：`slide.Shapes.AddShape(Office.MsoAutoShapeType.msoShapeRectangle, left, top, width, height)`。位置与尺寸参数皆为 float 类型。\n7. 修改文字内容时，如果需要查找并替换，可以遍历幻灯片中的 Shape 并检查 `shape.HasTextFrame == Office.MsoTriState.msoTrue && shape.TextFrame.HasText == Office.MsoTriState.msoTrue`。\n8. 请尽量编写健壮的代码，用 try-catch 包裹可能出错的地方，遇到不支持的操作时抛出异常。\n\n【核心PPT设计审美与排版规范（PPT Aesthetics & Layout Design Rules）】\n为了确保AI添加的PPT样式美观、专业且符合现代高端设计规范，请在编写代码生成/修改PPT内容时，严格遵守以下排版与审美原则：\n\n1. 配色系统与 60-30-10 黄金比例：\n - 禁止在没有用户明确要求的情况下使用刺眼的高饱和度纯原色（例如纯红 Color.Red、纯蓝 Color.Blue、纯绿 Color.Green、纯黄 Color.Yellow）。这会让 PPT 显得极不专业。\n - 使用成熟、高对比度且优雅的经典主题配色（使用 Color.FromArgb 定义颜色，然后使用 ColorTranslator.ToOle 转换）：\n * 极简科技蓝主题：\n - 主背景/主色：浅灰白 Color.FromArgb(248, 249, 250) 或 极深蓝 Color.FromArgb(10, 34, 64)\n - 辅助色/卡片背景：浅天蓝 Color.FromArgb(232, 240, 254) 或 经典蓝 Color.FromArgb(26, 115, 232)\n - 点缀强调色（10%）：温暖橙/金色 Color.FromArgb(245, 166, 35) 或 珊瑚红 Color.FromArgb(234, 67, 53)\n * 现代商务炭黑主题：\n - 主色：炭黑色 Color.FromArgb(43, 43, 43)\n - 辅助色：浅灰色 Color.FromArgb(240, 240, 240)\n - 点缀色：青/湖蓝色 Color.FromArgb(0, 168, 181)\n * 暖调人文/学术主题：\n - 主色：深林绿 Color.FromArgb(27, 67, 50)\n - 辅助色：柔和米色 Color.FromArgb(245, 242, 235)\n - 点缀色：赤陶红/土黄 Color.FromArgb(190, 130, 60)\n - 遵守 60-30-10 比例：背景占 60% 视觉面积，文字/卡片容器等次要元素占 30%，画龙点睛的重点高亮（如关键数字、重点结论词、边框线装饰）占 10%。\n\n2. 视觉层级与字号梯度（Visual Hierarchy & Text Scales）：\n - 建立清晰鲜明的字号差，中文默认使用“微软雅黑” (Microsoft YaHei)，英文默认使用“Segoe UI”：\n * 幻灯片大标题（Slide Title）：36pt - 44pt，粗体 (Bold)，深色高对比度。\n * 章节/卡片小标题（Card Header）：20pt - 24pt，粗体。\n * 正文内容（Body Text）：14pt - 18pt，常规体 (Regular)，中等对比度（如深灰）。\n * 关键数据/大数字（Big Stat/Metric）：48pt - 72pt 粗体，可搭配 12pt 的解释性小字。\n - 为确保文字排版完美，对所有新创建的文本框设置以下属性以防文本溢出或不对齐：\n * shape.TextFrame.WordWrap = Office.MsoTriState.msoTrue; // 开启自动换行\n * 适当清除或缩小默认内边距：\n shape.TextFrame.MarginLeft = 10f;\n shape.TextFrame.MarginRight = 10f;\n shape.TextFrame.MarginTop = 10f;\n shape.TextFrame.MarginBottom = 10f;\n\n3. 负空间与留白（Negative Space & Whitespace）：\n - 不要把幻灯片塞满！页面必须保留至少 30% - 40% 的空白区域，让观众的眼睛有呼吸的空间。\n - 绝不允许使用大段文字，请将文字提炼为短句，以列表或卡片形式展现。\n\n4. 动态网格布局与防重叠（Dynamic Grid Layout & Math Positioning）：\n - 永远通过代码动态获取幻灯片的物理大小，并在此基础上进行百分比定位或网格分栏计算，严禁使用写死的绝对坐标导致在不同比例的PPT中排版错乱：\n float slideWidth = Application.ActivePresentation.PageSetup.SlideWidth;\n float slideHeight = Application.ActivePresentation.PageSetup.SlideHeight;\n - 留出四周安全边距（Margin，通常设为 slideWidth * 0.06f 与 slideHeight * 0.08f）。\n - 如果需要展示并列的多个观点，应自动计算分栏位置：\n * 两栏布局：左栏占宽 45%，右栏占宽 45%，中间留空 10%。\n * 三分栏卡片布局示例：\n float margin = slideWidth * 0.05f;\n float availableWidth = slideWidth - 2 * margin;\n float gap = 20f; // 卡片间距\n float cardWidth = (availableWidth - 2 * gap) / 3f;\n float cardHeight = slideHeight * 0.5f;\n float top = slideHeight * 0.3f;\n for (int i = 0; i < 3; i++) {\n float left = margin + i * (cardWidth + gap);\n // 在 left, top, cardWidth, cardHeight 处绘制卡片容器\n }\n - 通过数学计算绝对保证生成的文本框、容器形状之间不会重叠。\n\n5. 扁平化容器卡片化（Flat Card-Based Design）：\n - 列表或并列观点应使用“浅色卡片”作为容器装载，卡片背景填充非常浅的颜色（如 RGB: 245, 245, 245），并且必须去掉边框轮廓以符合现代扁平化审美：\n cardShape.Line.Visible = Office.MsoTriState.msoFalse;\n cardShape.Fill.ForeColor.RGB = ColorTranslator.ToOle(Color.FromArgb(245, 245, 245));\n - 在卡片之上叠放文字形状时，通过 Y 坐标偏移（如 cardTop + 15 放置标题，cardTop + 45 放置正文）使排版整洁大方。\n - 尽量使用无轮廓（`Line.Visible = msoFalse`）的形状，如果使用线条，应保持极细（`Line.Weight = 1.0f`）且使用温和的淡灰色。\";\n }\n\n private void TxtInput_KeyDown(object sender, KeyEventArgs e)\n {\n if (e.KeyCode == Keys.Enter && !e.Shift)\n {\n e.SuppressKeyPress = true; // Prevent newline\n btnSend.PerformClick();\n }\n }\n\n private void ClearChat()\n {\n chatFlowLayout.Controls.Clear();\n conversationHistory.Clear();\n InitializeSystemMessage();\n }\n\n private void AppendBubble(string text, bool isUser, bool isSystem, bool isError = false)\n {\n // Strip emojis from the text to prevent square box characters in RichTextBox\n text = StripEmojis(text);\n\n ChatRowPanel row = new ChatRowPanel(text, isUser, isSystem, isError, chatFlowLayout.Width -

System\n - System.Collections.Generic\n - System.Linq\n - System.Drawing\n - System.Windows.Forms\n - Microsoft.Office.Interop.PowerPoint (别名为 PowerPoint)\n - Microsoft.Office.Core (别名为 Office)\n3. 安全获取当前幻灯片对象 (Slide) 的方法：\n PowerPoint.Slide slide = null;\n try { slide = Application.ActiveWindow.View.Slide as PowerPoint.Slide; } catch {}\n if (slide == null) {\n try { slide = Application.ActivePresentation.Slides[Application.ActiveWindow.Selection.SlideRange[1].SlideIndex]; } catch {}\n }\n if (slide == null) {\n throw new Exception(\"\"没有找到活动的幻灯片，请确保PPT处于正常视图。\"\");\n }\n4. 新增幻灯片页面请直接对 Application.ActivePresentation.Slides 进行 Add 或 Add2 操作，例如：\n var pres = Application.ActivePresentation;\n pres.Slides.Add(pres.Slides.Count + 1, PowerPoint.PpSlideLayout.ppLayoutBlank);\n5. 操作文字颜色时，请使用 `System.Drawing.ColorTranslator.ToOle(Color.Red)` 将颜色转换为 OLE 颜色。例如：\n shape.TextFrame.TextRange.Font.Color.RGB = ColorTranslator.ToOle(Color.Red);\n6. 插入形状时，第一个参数必须是 `Office.MsoAutoShapeType` 枚举类型（注意：千万不可写错成 `Office.MsoShapeType`，否则会报编译错误）。常用的形状枚举如下：\n - 矩形：`Office.MsoAutoShapeType.msoShapeRectangle`\n - 圆角矩形（注意是 Rounded，不是 Round）：`Office.MsoAutoShapeType.msoShapeRoundedRectangle`\n - 椭圆/圆形：`Office.MsoAutoShapeType.msoShapeOval`\n 示例：`slide.Shapes.AddShape(Office.MsoAutoShapeType.msoShapeRectangle, left, top, width, height)`。位置与尺寸参数皆为 float 类型。\n7. 修改文字内容时，如果需要查找并替换，可以遍历幻灯片中的 Shape 并检查 `shape.HasTextFrame == Office.MsoTriState.msoTrue && shape.TextFrame.HasText == Office.MsoTriState.msoTrue`。\n8. 请尽量编写健壮的代码，用 try-catch 包裹可能出错的地方，遇到不支持的操作时抛出异常。\n\n【核心PPT设计审美与排版规范（PPT Aesthetics & Layout Design Rules）】\n为了确保AI添加的PPT样式美观、专业且符合现代高端设计规范，请在编写代码生成/修改PPT内容时，严格遵守以下排版与审美原则：\n\n1. 配色系统与 60-30-10 黄金比例：\n - 禁止在没有用户明确要求的情况下使用刺眼的高饱和度纯原色（例如纯红 Color.Red、纯蓝 Color.Blue、纯绿 Color.Green、纯黄 Color.Yellow）。这会让 PPT 显得极不专业。\n - 使用成熟、高对比度且优雅的经典主题配色（使用 Color.FromArgb 定义颜色，然后使用 ColorTranslator.ToOle 转换）：\n * 极简科技蓝主题：\n - 主背景/主色：浅灰白 Color.FromArgb(248, 249, 250) 或 极深蓝 Color.FromArgb(10, 34, 64)\n - 辅助色/卡片背景：浅天蓝 Color.FromArgb(232, 240, 254) 或 经典蓝 Color.FromArgb(26, 115, 232)\n - 点缀强调色（10%）：温暖橙/金色 Color.FromArgb(245, 166, 35) 或 珊瑚红 Color.FromArgb(234, 67, 53)\n * 现代商务炭黑主题：\n - 主色：炭黑色 Color.FromArgb(43, 43, 43)\n - 辅助色：浅灰色 Color.FromArgb(240, 240, 240)\n - 点缀色：青/湖蓝色 Color.FromArgb(0, 168, 181)\n * 暖调人文/学术主题：\n - 主色：深林绿 Color.FromArgb(27, 67, 50)\n - 辅助色：柔和米色 Color.FromArgb(245, 242, 235)\n - 点缀色：赤陶红/土黄 Color.FromArgb(190, 130, 60)\n - 遵守 60-30-10 比例：背景占 60% 视觉面积，文字/卡片容器等次要元素占 30%，画龙点睛的重点高亮（如关键数字、重点结论词、边框线装饰）占 10%。\n\n2. 视觉层级与字号梯度（Visual Hierarchy & Text Scales）：\n - 建立清晰鲜明的字号差，中文默认使用“微软雅黑” (Microsoft YaHei)，英文默认使用“Segoe UI”：\n * 幻灯片大标题（Slide Title）：36pt - 44pt，粗体 (Bold)，深色高对比度。\n * 章节/卡片小标题（Card Header）：20pt - 24pt，粗体。\n * 正文内容（Body Text）：14pt - 18pt，常规体 (Regular)，中等对比度（如深灰）。\n * 关键数据/大数字（Big Stat/Metric）：48pt - 72pt 粗体，可搭配 12pt 的解释性小字。\n - 为确保文字排版完美，对所有新创建的文本框设置以下属性以防文本溢出或不对齐：\n * shape.TextFrame.WordWrap = Office.MsoTriState.msoTrue; // 开启自动换行\n * 适当清除或缩小默认内边距：\n shape.TextFrame.MarginLeft = 10f;\n shape.TextFrame.MarginRight = 10f;\n shape.TextFrame.MarginTop = 10f;\n shape.TextFrame.MarginBottom = 10f;\n\n3. 负空间与留白（Negative Space & Whitespace）：\n - 不要把幻灯片塞满！页面必须保留至少 30% - 40% 的空白区域，让观众的眼睛有呼吸的空间。\n - 绝不允许使用大段文字，请将文字提炼为短句，以列表或卡片形式展现。\n\n4. 动态网格布局与防重叠（Dynamic Grid Layout & Math Positioning）：\n - 永远通过代码动态获取幻灯片的物理大小，并在此基础上进行百分比定位或网格分栏计算，严禁使用写死的绝对坐标导致在不同比例的PPT中排版错乱：\n float slideWidth = Application.ActivePresentation.PageSetup.SlideWidth;\n float slideHeight = Application.ActivePresentation.PageSetup.SlideHeight;\n - 留出四周安全边距（Margin，通常设为 slideWidth * 0.06f 与 slideHeight * 0.08f）。\n - 如果需要展示并列的多个观点，应自动计算分栏位置：\n * 两栏布局：左栏占宽 45%，右栏占宽 45%，中间留空 10%。\n * 三分栏卡片布局示例：\n float margin = slideWidth * 0.05f;\n float availableWidth = slideWidth - 2 * margin;\n float gap = 20f; // 卡片间距\n float cardWidth = (availableWidth - 2 * gap) / 3f;\n float cardHeight = slideHeight * 0.5f;\n float top = slideHeight * 0.3f;\n for (int i = 0; i < 3; i++) {\n float left = margin + i * (cardWidth + gap);\n // 在 left, top, cardWidth, cardHeight 处绘制卡片容器\n }\n - 通过数学计算绝对保证生成的文本框、容器形状之间不会重叠。\n\n5. 扁平化容器卡片化（Flat Card-Based Design）：\n - 列表或并列观点应使用“浅色卡片”作为容器装载，卡片背景填充非常浅的颜色（如 RGB: 245, 245, 245），并且必须去掉边框轮廓以符合现代扁平化审美：\n cardShape.Line.Visible = Office.MsoTriState.msoFalse;\n cardShape.Fill.ForeColor.RGB = ColorTranslator.ToOle(Color.FromArgb(245, 245, 245));\n - 在卡片之上叠放文字形状时，通过 Y 坐标偏移（如 cardTop + 15 放置标题，cardTop + 45 放置正文）使排版整洁大方。\n - 尽量使用无轮廓（`Line.Visible = msoFalse`）的形状，如果使用线条，应保持极细（`Line.Weight = 1.0f`）且使用温和的淡灰色。\";\n }\n\n private void TxtInput_KeyDown(object sender, KeyEventArgs e)\n {\n if (e.KeyCode == Keys.Enter && !e.Shift)\n {\n e.SuppressKeyPress = true; // Prevent newline\n btnSend.PerformClick();\n }\n }\n\n private void ClearChat()\n {\n chatFlowLayout.Controls.Clear();\n conversationHistory.Clear();\n InitializeSystemMessage();\n }\n\n private void AppendBubble(string text, bool isUser, bool isSystem, bool isError = false)\n {\n // Strip emojis from the text to prevent square box characters in RichTextBox\n text = StripEmojis(text);\n\n ChatRowPanel row = new ChatRowPanel(text, isUser, isSystem, isError, chatFlowLayout.Width -
