Every pairing runs through the same 4-step checklist before it's published — contrast, spacing, scale, legibility.
Every downloadable pack and checklist is free. No paywalled "pro" tier hiding the fonts that actually work.
A pairing that only works on a 27-inch monitor isn't done. Every guide checks the size it will actually ship at.
One email a week, whenever a new pairing guide or font pack drops. No spam.
