            <p className="font-semibold text-foreground text-[11px]">1. 统一控件高度与投影：</p>
            <p>
              输入框 (<code className="bg-muted px-1 py-0.5 rounded font-mono">Input</code>) 与下拉选择器 (<code className="bg-muted px-1 py-0.5 rounded font-mono">SelectTrigger</code>) 的高度应统一限制为小号高度 <code className="bg-muted px-1 py-0.5 rounded font-mono">h-8</code>，字体大小使用 <code className="bg-muted px-1 py-0.5 rounded font-mono">text-xs</code>，并使用 <code className="bg-muted px-1 py-0.5 rounded font-mono">shadow-none</code> 去除原生的重叠阴影。
            </p>

            <p className="font-semibold text-foreground text-[11px] pt-1">2. Checkbox 与文本的对齐：</p>
            <p>
              Checkbox 应在左侧垂直偏上对齐，使用容器 <code className="bg-muted px-1 py-0.5 rounded font-mono">flex items-start gap-2.5</code> 排列。Checkbox 组件本身添加 <code className="bg-muted px-1 py-0.5 rounded font-mono">mt-0.5</code>，从而在多行描述文本的情况下依然保持良好的顶对齐，避免出现居中对齐导致的凌乱感。
            </p>

            <p className="font-semibold text-foreground text-[11px] pt-1">3. 按钮使用策略：</p>
            <p>
              普通主表单及新增/保存按钮，一律使用默认 Primary 按钮或次要 <code className="bg-muted px-1 py-0.5 rounded font-mono">{'variant="secondary"'}</code> 按钮，小号高度统一采用 <code className="bg-muted px-1 py-0.5 rounded font-mono">h-8 text-xs</code>。线框按钮必须带有 <code className="bg-muted px-1 py-0.5 rounded font-mono">border-dashed shadow-none</code> 类。
            </p>
          </div>

          <div className="bg-background/80 p-3 rounded border border-border/40 font-mono text-[10px] space-y-2 overflow-x-auto">
