was running into the same issue here:

TypeScript error in /app/src/App.tsx(17,20): Type '{ global: { colors: { brand: string; focus: string; placeholder: string; control: string; }; font: { family: string; size: number; }; input: { weight: number; padding: string; }; edgeSize: { small: string; }; }; ... 6 more ...; textArea: { ...; }; }' is not assignable to type 'ThemeType'.

turns out, we hadn’t added a typescript loader to our app. app now runs after following the instructions here: https://ricostacruz.com/til/babel-typescript
