What is the problem?
给中文新手的 Cloudflare 和 Namecheap 域名选择流程：先看是否需要独立 nameserver、DNS 管理、账单边界、客户授权和后续交付记录，再决定是否购买或迁移。
Quick solution
Treat this as a Vercel tutorial issue. First confirm the environment, inputs, permissions, logs, and delivery boundary. Then use the linked deep guide for the full checklist before changing production code or promising a result.
Read the deep guideDetailed steps
- 写清用途：作品集、客户测试站、正式官网、邮箱域名、API 域名，还是临时演示域名。
- 确认域名所有权：个人练习可以自己持有；客户项目应优先由客户账号持有，你只记录建议和操作步骤。
- 查当日总成本：首年价格、续费价格、隐私保护、PremiumDNS、转入转出和可能的税费都要单独看。
- 判断 DNS 需求：只需要 A/CNAME/TXT 记录，还是需要邮箱、DNSSEC、子域名委派、多个环境和更细的权限。
- 判断 nameserver 是否需要自由切换：如果必须长期用 Cloudflare DNS，Cloudflare Registrar 更顺；如果要保留切换空间，Namecheap 或其他注册商可能更灵活。
- 保存交付记录：域名、注册商、DNS 服务、关键记录、变更时间、验证结果、待确认事项。

Risk notes
Confirm the real project environment, account permissions, platform rules, and output quality before delivery. Do not ship AI-generated changes without human review, and do not claim indexing, income, deployment success, or ranking improvements without measured evidence.
