/* ---------------------------------------------------------------------------
 * 选项组 + 选项行(1.5.1 重排)
 *
 * ⚠ po.css 在 flatsome.css 之前加载,而主题对 label / legend / input[type=number]
 *   有全局样式(输入框 width:100% + 下外边距、label 加粗缩字号、legend 上下大外边距……),
 *   同优先级甚至更高 → 会盖掉这里。所以下面凡是要压主题的规则都挂在 .sig-po-overlay 下,
 *   把优先级拉到主题之上。改这一段时别把前缀去掉。
 *
 * 一行的布局:[勾选框] [配图] [名称 —— 占满剩余宽度] [+价格 右对齐] [份数框 固定窄宽]
 *   名称吃掉中间所有空间 → 价格、份数框永远贴右,逐行竖向对齐成一条线;
 *   名称只有在一行真放不下时才折行。
