1//! [`Spacing`]: design-system spacing scale in pixels.
2
3/// Design-system spacing scale, in pixels.
4///
5/// Mirrors libcosmic's `space_xxxs` through `space_xxxl` scale. Widgets
6/// reference these values rather than hard-coding pixel counts, so the
7/// entire UI scales coherently when a theme is swapped.
8///
9/// Default values are tuned for a 320×240 display at 1× density. For
10/// larger displays consider scaling proportionally.
