/**
 * Shared loading fallback for the dashboard segment. It is the Suspense
 * fallback for Hem (app/(dashboard)/page.tsx) and for every child route that
 * has no loading.tsx of its own, so it deliberately mirrors Hem's silhouette:
 * a greeting hero (H1 + date line) followed by a single "Att göra"-style pane
 * of list rows (see DashboardContent / AttGoraSection).
 *
 * A greeting + hairline-separated rows reads honestly on Hem and stays neutral
 * on the plain list pages that fall back here (a page title + rows), which is
 * why it is not shaped like any one page's specific grid.
 *
 * /chat is the exception: MainContainer renders it full-bleed (no max-width,
 * no padding), so the column silhouette would stretch edge-to-edge and read
 * broken. The chat branch mirrors the two-pane chat shell instead:
 * conversation sidebar + empty conversation pane (see ChatLayout/ChatSidebar).
