[mdmower-csnw]

This is a testing pull request for uswds/uswds-compile#145 . It is not intended to be merged. Once testing is complete, this pull request can be closed.

uswds/uswds-compile#145 adds support for configuring sass-embedded via settings.compile.sassOptions. It also deprecates but maintains compatibility for settings.compile.sassDeprecationWarnings. Sample code changes are applied in this PR to demonstrate use of this new option.

Suggested tests to get started

1. Custom loadPaths and unminified CSS
   1. Use this PR as-is
   • Compilation should succeed, SASS deprecation warnings should be suppressed, there should be italicized text on the home page, and the output _site/assets/css/styles.css should not be minified. If the watch script is running, editing _custom.scss should result in SASS recompilation.
2. Undefined options
   1. Update src/_styles/_uswds-theme-custom-styles.scss: replace @use "custom"; with @use "../custom/custom";.
   2. Update gulpfile.js: comment out assignment of uswds.settings.compile.sassOptions.
   • Compilation should succeed, SASS deprecation warnings should be suppressed, there should be italicized text on the home page, and the output _site/assets/css/styles.css should be minified.
3. Deprecated option
   1. Restore files to match this PR
   2. Update gulpfile.js: add settings.compile.sassDeprecationWarnings = true;
   • Compilation should succeed, SASS deprecation warnings should not be suppressed, there should be italicized text on the home page, and the output _site/assets/css/styles.css should not be minified.

From here, feel free to play around with additional options.
