Uses the 'email' input type for the submission and support email addresses.

Visually they look the same, but some mobile browsers will respond to the email input type by prompting the user with an email keyboard (where things like the @ and domain suffixes are more prominent). This means entrering an email address requires fewer keystrokes, which is a general usability improvement but can particularly make life easier for users with motor disabilities.

Things to consider when reviewing

• Ensure that you consider the wider context.
• Does it work when run on your machine?
• Is it clear what the code is doing?
• Do the commit messages explain why the changes were made?
• Are there all the unit tests needed?
• Do the end to end tests need updating before these changes will pass?
• Has all relevant documentation been updated?

It may take 5 minutes or so for the application to be fully deployed and working. If it still isn't ready
after 5 minutes, there may be something wrong with the ECS task. You will need to go to the integration AWS account
to debug, or otherwise ask an infrastructure person.
