 * Layout primitives, replacing Bootstrap 3.3.1 (MIT). Only what this site uses: the base resets and typography
 * sizes the grayscale theme builds on, the fixed-width container, the grid columns in use, the navbar structure,
 * and the button/list resets. Values are Bootstrap's own, so the rendering is unchanged.
 * Class names are kept (.container, .row, .col-*, .navbar-*) because css/grayscale.css styles them.
