## Pairing & Compatibility

### Typography pairing

Micro Line

- Primary: Choose simple letterforms with a weight close to the artwork. For example, try Inter. Try 11px or 12px text, then adjust it to suit the layout.
- Alternative: Try structured letterforms to echo the geometric shapes. For example, try IBM Plex Sans.
- System fallback: Choose simple letterforms with a weight close to the artwork. For example, try -apple-system, system-ui.
- Caution: Compare heavier or decorative type at the final size so it does not overpower the artwork.

Micro Solid

- Primary: Choose simple letterforms with a weight close to the artwork. For example, try Inter Medium.
- Alternative: Choose simple letterforms with a weight close to the artwork. For example, try IBM Plex Sans.
- Dark UI: Choose enough text weight to balance the heavier parts of the artwork. For example, try Inter SemiBold.
- Caution: Check that fine text remains visible beside heavier artwork.
