A transparent footer with a two-line sign-off and a Start Now button. Link Group component props: heading, link1Label/link1Href … link4Label/link4Href. Each group is a native details/summary element: on phones it folds into an accordion (tap, Enter, no script needed), and on wider screens the markers disappear and all four groups sit open, side by side. A legal row with a Back to top link closes the footer. Entirely CSS-driven.
