- rsvpLink() now appends &lang=<en|fr> when generating a recipient's personal
link, so the English invitation's link opens the English RSVP form instead
of defaulting to French. Threaded through sendTest and the mass-send worker.
- New optional per-language "address" field (editor input, SEED default for
fete-20-ans, Unlayer template var), rendered under the date with a pin icon
in both the festive email and the RSVP page.
- Logo: +20px bottom margin in both the email template and the RSVP page.
