Here is how your PR affects size of JS and CSS bundles shipped to the user's browser:

Async-loaded Components (~353 bytes added 📈 [gzipped])

name                               parsed_size           gzip_size
async-load-automattic-help-center       +943 B  (+0.1%)     +353 B  (+0.2%)

React components that are loaded lazily, when a certain part of UI is displayed for the first time.

What is parsed and gzip size?

Parsed Size: Uncompressed size of the JS and CSS files. This much code needs to be parsed and stored in memory.
Gzip Size: Compressed size of the JS and CSS files. This much data needs to be downloaded over network.

I believe we don't need the
/* stylelint-disable-next-line declaration-property-unit-allowed-list */
And we can use $font-body;
