Dashboard
Named grid areas: an "app shell". The areas template paints a picture of the layout; each child places itself into a named region with area="...", and a name repeated across cells spans them (header and footer span both columns). columns="150px 1fr" and rows="56 1fr 42" size the tracks; the 1fr column and row fill. The main region hosts a lazy <plot> that reflows to fill it, and the sidebar a nested stretch column of nav buttons.
