The '>' characters at the end of emails were caused by Rails development
mode adding HTML comment annotations to rendered views, including email
templates. This creates comments like '<!-- END app/views/...erb -->'
which can appear as stray characters in email clients.
Solution:
- Add initializer to disable view annotations specifically for ActionMailer
- Preserves debugging annotations for regular views
- Ensures clean email formatting in development mode
- No impact on production where annotations are disabled by default
The emails will now render cleanly without extra HTML comments or
stray characters at the end.
