Susy

Allows building any grid system without pre-defined constraints, enabling tailored layouts that fit specific design needs, as emphasized in its philosophy.

Core grid-math functions (Su layer) use normalized values for precise control, letting developers handle complex layout logic directly, as outlined in the Su vs Susy section.

Focuses on providing tools rather than opinions, adapting to any design requirement, which is central to its value proposition for custom systems.

The Susy layer offers shorthand parsing and global defaults, simplifying common tasks while maintaining flexibility, as described in the README's layer distinction.
