- 版式参照单据样板：公司抬头 + 两行三列表头 + 统一明细列 （商品编号/名称/系列/规格/批次号/生产日期/数量/单价/金额/备注） - 单据总计独立成行（仅数量+金额，右对齐高亮） - 出库单保留温馨提示，入库单去掉 - 签字行：制单人=当前登录用户(OrderPrintMeta)，采购员/销售员=经办人； 公司名取门店(shopInfoProvider) - 出库单单价=售价(sale_price)，金额=售价×数量；历史单 sale_price=0 时回退 unit_price/total_price。入库单单价=进价(unit_price) - 桌面 PDF 与 Web HTML 两端同构 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
