This was just paranoia, but I wanted to add a test that referencing an alias without any . in it worked. I just realized that’s untested. Fortunately that was unrelated to #191

const json = {
a: {$type: 'number', $value: 2},
b: {$type: 'number', $value: '{a}'},
};
const tokens = getTokens(json);
expect(tokens.find((t) => t.id === 'a')?.$value).toBe(json.a.$value);
expect(tokens.find((t) => t.id === 'b')?.$value).toBe(json.a.$value);
});

const json = {

Simple fix: typography tokens get “hoisted” (for lack of a better term) in plugin-css, but in some instances this has already been transformed to a CSS variable (a string).

for (const [k, v] of Object.entries(value)) {
tokenVals[generateName(`${token.id}-${k}`, token)] = v;
}
} else {
tokenVals[ref] = value;
}
break;
}

Also tested border and gradient tokens to make sure it wasn’t happening with other composite types
