On the last day of UAT for our account opening system, two defects come in. The bank logo is misaligned on the confirmation page. And for joint accounts, the second holder's date of birth isn't being saved, which affects about 3% of new accounts. How would you rate severity and priority for each, and which one has to be fixed before go-live?

开户系统 UAT 最后一天冒出两个缺陷：一个是开户成功页上的银行 logo 错位；另一个是联名账户第二持有人的出生日期没存进系统，大概影响 3% 的新开户。这两个缺陷你怎么定严重度和优先级？哪个必须上线前修好？
