【项目名称】天龙四驱 · 会员消费价格计算器
【当前版本】V2.1
【开发时间】2026-07-15
【更新说明】配件行增加工时费/运费字段，按配件汇总计算工时应付与运费，去除全局工时输入框
【功能需求总汇总】
1、基础功能
   1.1、包含四种会员类型：非会员、基础会员、进阶会员、超级会员
   1.2、每种会员可自定义：年费、年度进货限额、超限配件折扣、工时折扣
   1.3、超级会员文案简化为：年度进货价限额（无上限），默认值9999999代表无上限
   1.4、页面默认选中【进阶会员】，默认高亮对应卡片

2、计算核心业务规则（最终定稿）
   2.1、新增多配件模块：动态增删配件，每一项包含：配件名称、数量、单价市场价、单价进货价
   2.2、自动实时汇总：总市场价=所有配件(数量*单价市场价)之和；总进货价=所有配件(数量*单价进货价)之和
   2.3、读取参数：自动汇总总配件市场价、自动汇总总配件进货价、会员已使用年度额度、本次工时原价
   2.4、计算剩余年度限额 = 会员年度总限额 - 已使用额度
   2.5、分支1：本次总进货价 ≤ 剩余限额 → 配件应付 = 总进货价（全额支付进货价，无超限费用）
   2.6、分支2：本次总进货价 ＞ 剩余限额 → 配件应付 = 剩余免费额度 +（总市场价-剩余额度）× 会员超限折扣系数
   2.7、工时费用 = 工时原价 × 对应会员工时折扣系数
   2.8、总支付金额 = 配件应付金额 + 折扣后工时费用
   2.9、非会员：配件全额按总市场价支付，工时无折扣

3、交互体验需求
   3.1、废除【立即计算】按钮，全程输入/增删配件实时自动计算
   3.2、所有文本、数字输入框获取焦点自动全选内容，支持直接覆盖修改，无需手动删除
   3.3、切换会员类型、修改会员参数、修改配件列表、修改已使用额度/工时，实时刷新汇总与计算结果
   3.4、自动同步更新工时费率标签文字，展示当前会员折扣
   3.5、配件列表支持新增行、删除单行，任意字段修改立即重新汇总

4、UI与适配需求
   4.1、深色主题、橙色主题色，卡片式布局，选中会员卡片高亮
   4.2、精简计算结果字段，只保留核心收款展示数据，去除冗余优惠字段
   4.3、全设备自适应：电脑4列、平板2列、手机1列，完美适配手机/平板/电脑
   4.4、禁止页面缩放、适配手机视口，输入框触控优化，小屏不溢出、不挤压

5、结果展示字段（最终保留）
   1. 配件汇总总市场价
   2. 当年剩余可用进货限额
   3. 超出限额对应市场价
   4. 配件合计应付金额
   5. 工时费应付金额（折扣后）
   ★ 本次实际待支付总金额
