/* 商品使用 · 商品位 + 人物位（并排）+ 出图比例选择
 * ============================================================================
 * 只做本功能需要的两块：并排双上传位（商品必填 / 人物可选）、比例胶囊。
 * 其余（banner / 卡片 / 补充要求 / 效果示例 / 结果区 / toast）复用 xt-* 与 ix-*。
 * ⚠️ 按项目规约：所有选择器带 #sub-productuse 作用域，不碰 style.css。
 * ⚠️ 类名统一 pu- 前缀，与其它功能的 of-/fm-/ms- 不重名。
 * ========================================================================== */
