From the spec chapter I linked to in my original comment:
> Any identifier which could be misinterpreted as a pre-defined keyword in the font-family value definition, or the CSS-wide keyword values, is not allowed.

This text is very clear that if you say `h1 { font-family: system-ui; }`, you will *always* get the browser built-in font, not a webfont. The only way to access a `@font-face { font-family: system-ui; ... }` is by writing `h1 { font-family: "system-ui"; }`. (And `font-family: "system-ui";` should *never* select the browser built-in, even if there's no webfont defined for that name.)
