[spike] - general redesign of UI to soften edges of buttons

[rachel-labri-tipton]

Detailed Description

General redesign of the web app UI to soften the edges of buttons etc.
This was suggested by our previous designer, Elisabeth. Not necessary, but could spend a time-boxed commitment to see what this looks like.

Context

The rounded edges on the mobile app look good. It could be nice to update the look and feel of the web app.

Possible Implementation

• Have a look at the mobile app styling.
• Play around with the look and investigate how long it might take to implement changes.
• Talk to users.
