1//! UI sizing, typography, icon sizes and keyboard focus helpers.
2//!
3//! UI colours, text, spacing and radii come from the applied [`Theme`](crate::theme::Theme).
4//! These modules retain fixed component dimensions and the default font sizes used by
5//! the theme. See `docs/theme.md` for runtime customisation.
