Note to update Sass code:

The Sass map-get() function is going to be deprecated in future versions of Dart Sass. It will still work currently, but if you'd like to get ahead of the change, you can make the following changes to the _breakpoints.scss file:

At the top of the file, add @use 'sass:map';

In the breakpoint() and breakpoint-down() mixins, replace map-get() with map.get()
