+      Settings mode's own furniture: a page title, a tracked section label, a card group and the rows inside
+      it. Named apart from Border.section and TextBlock.sectionlabel above rather than reusing them — those
+      are the hosts drawer's 320-pixel column, at that column's own padding and heading size, and the
+      settings pages are a 1100-pixel one at the numbers Settings-General.dc.html and its three siblings all
+      state identically: 12-radius cards on Raised with a 1px Border inset, 20/24 row padding, a 1px
+      BorderSubtle divider between rows and none under the last one.
