Verify Email Snapshots

Email templates break in subtle ways that unit tests miss. This uses Verify to snapshot the full rendered HTML of your email templates, so when something changes, you get a visual diff instead of a cryptic assertion failure. Works with MJML or any email renderer. You write a test that renders a template with sample variables, and Verify captures the HTML as a baseline. Next time it runs, any difference fails the build until you review and accept it. The real win is catching regressions during code review when someone tweaks a layout or variable substitution. Pair it with a diff tool or just open the HTML in a browser to see what actually changed.
