Masu: Site title font size differences in enviroments

[iamtakashi]

Quick summary

I've noticed that the site title is larger than how it should be in Masu on WP.com.

On a self-hosted site with a Gutenberg trunk, the fluid font size is determined by: (Correct)

.wp-block-site-title {
    font-size: clamp(1.125rem, 1.125rem + ((1vw - 0.48rem) * 0.721), 1.5rem);
}

But this is how it's been done on a WP.com site: (Wrong)

.wp-block-site-title {
    font-size: clamp(1.125rem, 1.125rem + ((1vw - 0.48rem) * 2.163), 2.25rem)
}

Localhost	WP.com

Steps to reproduce

1. Activate Masu theme in a WP.com test site
2. Activate Masu theme in a self-hosted/localhost test site.
3. See the difference in the site title block.

What you expected to happen

The site title should be the same.

What actually happened

The site title on WP.com is much larger.
