This panel is only visible on localhost.

Mock mode (no email sent, link shown on page):

• Use any address ending with .yyy, e.g. you@test.yyy
• Also triggered when no Resend:ApiKey is configured
• Dev TLDs: .test · .local · .dev · .example · .yyy

Simulate send failure (tests the error banner):

• Use any address ending with .error, e.g. you@test.error

Real email (requires Resend API key):

• Use a real address — email is sent via Resend if Resend:ApiKey is set
