Notes

sass-resources-loader imports specified SASS files into every SASS file it processes. In this particular case, styleLoaders are (Bootstrap 3, development):

- style-loader
- css-loader
- sass-loader
- postcss-loader
- sass-resources-loader?resources=app/styles/resources.scss

So, app/styles/resources.scss is implicitly imported into app/styles/bootstrap/pre-customizations.scss among other things. There $custom-border-radius value is assigned to $alert-border-radius. You can see the alert affected at the bottom of the page.
