Send Reshareable Greeting Card (function)

[Timebox: 2 hours, Complexity Points: 2]

As a developer, I need functionality to send a short email, including the sender’s name, that I can run when the user performs the “send” action.

**User Expectations:**

- When the user performs the “send” action (see “Send Method/Action” user story), the card will be sent by email
- Email is sent to the specified email address, containing a short message saying who the greeting card is from

**Developer Dependencies:**

- Send Method/Action (button)
- JS mail method: window.open('mailto:test@example.com?subject=subject&body=body');
- Required Fields:
- Greeting (dear loved one)
- Body (Love you much!)
- Closing (love, your kid)

Start from the Send Method/Action button and the JavaScript mail method mentioned in the issue. Verify how the specified email address and required Greeting, Body, Closing, and sender name are supplied; done means the send action opens an email containing the short greeting-card message.
