{{-- The utility foot of the navy column, added through PanelsRenderHook::SIDEBAR_FOOTER. Two things that belong to the navigation rather than to the page: the link out to the live site, because editors work in here and check the result out there, and the regulated mark, which is what the public footer signs off with. Both were briefly carried in the footer bar; they came back here when the sidebar became a single navy column running the full height of the screen, because a white mark needs a dark ground and a "leave the panel" link belongs beside the links that move around inside it. Flush with the navigation above it — one hairline, the same gutters, no box — so the navy reads as one uninterrupted surface top to bottom. Values come from config('site.*'), which the settings table overlays at boot, so a change made in Site settings reaches this foot with no edit here. Plain anchor and an existing asset. No new route, no new behaviour. --}}
