+/**
+  Calculate the shared page-list row layout for setup pages.
+
+  DashboardDensity reuses the app-owned density preference so secondary setup
+  pages follow the same compact/comfortable visual rhythm as the Dashboard.
+  Compact uses shorter rows and less padding; Comfortable preserves the
+  original list spacing as closely as possible. The helper also owns the
+  Devices preview split so drawing and navigation share one row-cap decision.
+
+  @param[in]  Ui                Initialized render context. Must not be NULL.
+  @param[in]  DashboardDensity  Dashboard density preference. Compact selects
+                                the compact list metrics; all other values use
+                                comfortable metrics.
+  @param[in]  HardRowCap        Maximum rows the caller may show. Zero means no
+                                selectable rows are requested.
+  @param[in]  AllowPreviewPane  TRUE when the page can use a right preview pane.
+  @param[out] Layout            Receives the panel and list metrics. Must not be
+                                NULL. Zeroed on entry; left zeroed on FALSE.
+
+  @retval TRUE   The content rect can host at least one requested row.
+  @retval FALSE  Ui or Layout is NULL, HardRowCap is zero, or rows do not fit.
