What's inside each TTF zip?
Normal/
Hinted/ ← standard-DPI (most Windows)
Unhinted/ ← high-DPI / Retina (macOS, Linux)
SemiCondensed/
Hinted/
Unhinted/
Condensed/
Hinted/
Unhinted/
Install all fonts in your chosen folder — your OS exposes the full weight axis (Thin → Black) automatically. Start with Normal/ if you're unsure.
