Prop types and inline documentation are included below. This is repository source; the installer rewrites shared imports for your project.

/**
 * A `<fieldset>`/`<legend>` pair around real radio inputs. The legend is the
 * group's name read once by a screen reader on entry — the piece a `<div>`
 * of styled buttons with `role="radio"` sprinkled on has to reimplement by
 * hand and usually gets half right.
