Five things it should do before it earns the name.
Colour, spacing, radius and the type scale are declared once and read everywhere, so a change lands in a single edit.
Each component carries its own styles and needs no global stylesheet, so moving it to another project is one file.
Empty, loading, error and disabled are designed alongside the happy path instead of appearing when a ticket does.
Focus order, contrast and reduced-motion behaviour live inside the component rather than in a later audit.
Every part ships with a README and a live demo at three widths, so usage notes cannot drift far from the source.
A part that needs three imports and a build step to run elsewhere is not reusable, only well organised. Everything here is meant to survive being pasted into a project that knows nothing about this one.
