Several environment variables are used to configure the application at build-time. None of these values are required during testing.

* `GA_PROPERTY` - Google Analytics property ID.
* `SENTRY_KEY` - Sentry.io DSN key for error reporting.
* `CIRCLE_BRANCH`, `CIRCLE_BUILD_NUM`, and `CIRCLE_SHA1` - CircleCI values used to generate build ID. Displayed in application footer and used in Sentry.io error reports.
* `DEPLOY_BUCKET` - AWS S3 bucket to deploy application to when running `yarn deploy`.
* `DEPLOY_ENV` - Environment the applicatoin will be deployed to. Used to report environment in Sentry.io error reports. Typically set to either "preview" or "production".
* `BANNER` - Text to display in header banner. Generally generated from `NODE_ENV`
* `BUILD_ID` - Application build ID. Generated from `CIRCLE_BRANCH`, `CIRCLE_BUILD_NUM`, and `CIRCLE_SHA1` if not set.
