Foundations
Spacing and sizes
Gutters, the space scale behind the spacing utilities, and control sizes.
Values in pt. Every control keeps a 44 × 44 hit area whatever its visual size. Home opens the core sheet at half; the sheet cannot be dismissed. The tab bar and map controls are the system's (Liquid Glass tab bar for Home, Nearby and Search; MapKit controls), and detail overlays own a 44pt xmark at the top trailing corner.
Spacing
Space scale
Spacing utilities (.ct-m-*, .ct-p-*, .ct-gap-*) are generated from this scale.
