/**
 * Hero slider (ADO #41324).
 *
 * Colours are fixed here on purpose: the text sits on photography and has to
 * stay legible, so an editor can change typography, sizes and spacing through
 * the Elementor controls but not the palette. The single exception is the arrow
 * background, which has its own control because it must adapt to the photo.
 *
 * Sizes and spacing that the client should control are driven by Elementor
 * selectors, so avoid hard-coding those unless they are structural.
