/* 正文区是 flex 列容器，且自己承担滚动（.lb-img 与 .lb-body 各自独立滚动）。
   三个条件缺一不可：
     ① min-height:0 —— grid/flex 子项默认 min-height:auto 会拒绝收缩，
        去掉它整行会被内容撑到 2000px+，再被 .lb-panel{overflow:hidden} 裁掉；
     ② 子项 flex:none —— 否则高度受限时 flex 会把可缩的子项压扁
        （.lb-prompt 曾被压到只剩 32px 高而内容有 1755px，表现为"提示词被截断"）；
     ③ .lb-prompt 自身不设 max-height/overflow —— 滚动只由本容器一层承担，
        避免嵌套滚动容器让手指划错目标。 */
