Let me check the files for encoding issues:

The hydration error is caused by toLocaleString() producing different output on the server vs client (since locale/number formatting can differ between environments). I also see new Date().toISOString() in addLog which can cause mismatches. Let me fix these issues:

Now add mounted state and expose formatNumber in the provider:

Now fix service-cards.tsx to use formatNumber instead of toLocaleString:

Now fix brand-header.tsx which also uses toLocaleString:

Now let me check if any other files also use toLocaleString:

There are several more files with toLocaleString. Let me read and fix them all:

Now I need to fix all the remaining toLocaleString() and new Date() calls. Let me fix all files:

Now fix gift-confirm.tsx - it has toLocaleString and new Date().toLocaleDateString:

Now fix info-query.tsx:

Now let me verify there are no remaining toLocaleString calls in our custom components (excluding built-in UI components like chart.tsx and calendar.tsx):

所有自定义组件中的 toLocaleString 都已替换完成。水合错误的根因是 toLocaleString() 和 new Date().toLocaleDateString() 在服务端和客户端可能产生不同的格式化输出（因为 locale 环境不一致），导致 SSR 和客户端渲染的 HTML 文本不匹配。修复方案是用一个确定性的 formatNumber 工具函数（基于正则的千分位分隔）替代所有 toLocaleString 调用，同时将动态日期替换为静态字符串，确保服务端与客户端输出一致。

Let me first understand the current codebase structure and the gift flow:

Now I understand the full flow. I need to:

1. Add "gift-address" to the PageRoute type
2. Create the address form component
3. Update gift-detail.tsx to navigate to address page instead of confirm
4. Update gift-confirm.tsx to show address info
5. Update app/page.tsx to include the new route

Let me also check the sub-page-header:

Now I have full context. Let me make all the changes. First, add gift-address route and address state to the context:

Now update gift-detail.tsx to navigate to the address page instead of directly to confirm:

Now create the address form component:

Now update gift-confirm.tsx to show the saved address info:

Now add address display section in the confirm page, after the gift summary card:

Now update app/page.tsx to include the new route:

已完成地址填写表单页的开发。新增 gift-address 路由页面，包含收货人姓名、手机号（失焦时中间4位掩码）、省市区三级级联下拉框（覆盖湖南省全部地市及常用省份）、详细地址文本框、默认地址复选框，以及"保存地址并确认兑换"（品牌红色）和"取消"（灰色）两个操作按钮。表单内置完整校验逻辑：必填项红色高亮提示、手机号11位格式校验。整个流程改为：礼品详情 -> 地址填写 -> 兑换确认（含地址信息展示和修改入口），符合中国人寿品牌风格。
