/* page-base.css — drop-in responsive foundation for any published page.

 * responsive grids, image scaling, table scroll, focus states, reduced motion —
 * so you never re-author this boilerplate and pages are responsive by default.
 *
 * Theme it by changing only the variables in the first :root block. */
