The app attempts to match the theme that the frontend is currently using. Theme keys that the app will use are:
primary-background-colorfor the background color of the web view
primary-colorfor the status bar background color
text-primary-colorfor the pull to refresh tint color
Themes should update in real time. Only system themes, not user themes, are supported. Colors should be specified in hex format (e.g.
#0099ff) and defining element colors through variable names is not supported.
