apx-ds engine
The engine behind apx-ds: a single generic core every component is built on. It owns variant logic, design-token resolution, responsive prop resolution ({ base, sm, md, lg, xl }), animation primitives, and class merging — so behavior is defined once and shared, never re-implemented per component. Framework-thin and feature-rich, it's what makes the whole design system configurable and overridable at every level.
- One place for variant logic, token resolution, responsive props, and motion — every component imports it, nothing is duplicated.
- Responsive resolver turns a single value or a { base, sm, md, lg, xl } object into CSS in one pass.
- Shared animation primitives and class-merging utilities across the library.
