对比图 / 矩阵图
适用于：方案对比、功能矩阵、技术选型等多选项按多维度比较的场景。
Content 约束
- 每格内容要充实：不要只写一个关键词，给出具体说明（如"MVCC 多版本并发控制，支持行级锁"而非仅"支持"）
- 单格内容不同格子允许不同长度，但每格不超过 5 行
- 长文本（超过 15 字）用
textAlign: "left"（不要居中） - 第一行是标题行（对象名称），第一列是维度标签列
- 维度数量至少 4 个，充分展开对比维度
Layout 选型
| 模式 | 适用条件 | 特征 |
|---|---|---|
| 严格 grid（默认） | 所有对比场景 | 表头行 + 数据行，每行 horizontal frame，行内 rect 等分 |
| 卡片式对比（替代） | 维度较少（2-3 个） | 每个对象做一张独立卡片，卡片内纵向列出各维度。卡片横向等分：外层 layout: "horizontal"，每张卡片 width: "fill-container" |
Layout 规则
- 最外层 frame：
layout: "vertical"，固定width（如 1000），height: "fit-content" - 每行：horizontal frame，
width: "fill-container"，alignItems: "stretch" - 行内单元格全部
width: "fill-container"等分列宽 - 行间
gap >= 12（不要 8，太紧） - 行内列间
gap: 8-12 - 标题行：深色底白字（由 style 控制具体颜色）
- 每列同色边框保持视觉一致性
- 单元格
height: "fit-content"，不要写固定 height

陷阱
- 行间距 8px 太紧：行间 gap 至少 12，8 会让行与行视觉粘连。
- 长文本居中对齐：超过一行的文本应改为
textAlign: "left"，居中多行文本可读性差。 - 列数太多导致每列太窄：对比对象建议 ≤ 5 列（含维度列），超过时合并维度或拆分为多张表。
- 列宽不等：所有数据列必须用
width: "fill-container"等分，不要给某列写固定宽度。 - 行高不等：每行 frame 必须
alignItems: "stretch"，否则同行单元格因文字行数不同高矮不齐。 - 忘记维度标签列：第一列放维度名称，标题行（维度列）用与数据列不同的视觉处理。
- 单元格用固定 height：单元格必须
height: "fit-content"，固定高度会导致文字截断。
