/*!
 * Brooks Law — UI components (v4.12)
 *
 * Four patterns borrowed from the federal design system that this theme did
 * not have: a numbered process list, a callout box, post navigation, and a
 * return-to-top control.
 *
 * Colours reuse the theme's own custom properties where they exist and fall
 * back to literals only when a property is not defined, so these components
 * follow the Design Studio settings rather than introducing a third palette.
