- Button · Button
The ranked action. One primary per screen, then secondary, tertiary, ghost and the two danger forms. Labels say what happens: "Publish to brands", "Save draft", "Sync cloths". - Icon button · Button
A square button that carries only an icon: row menus (⋯), edit, close, remove. Always named for assistive tech and usually paired with a tooltip. - Link button · Button
An anchor styled as a button, for navigation that looks like an action ("Open order", "View in Global Store"). Kit v2 scopes the link-colour reset so a page's `a{color:inherit}` cannot strip a filled button.
