FAQs

Why does Castoro make sense as the lead font?

Castoro owns the emotional register of this system. Its text, academic, readable profile helps anchor campaign creative, meaning marketing and product teams can reuse the same voice without reinventing the scale.

Where should Space Grotesk show up?

Space Grotesk is the workhorse. Keep it in paragraphs, long-form editorial, knowledge bases, or anywhere legibility is non-negotiable. Its quirky, monospaced-feel, brutalist qualities reduce fatigue on dense layouts.

Does this pairing support complex localization?

Yes—both families are available on Google Fonts with generous glyph coverage. Test cyrillic/latin accents early, but most Latin-based locales and UI patterns are fully supported.
