/*!
 * Theme Engine — shared styles for RefBytes themes for Omeka S.
 *
 * Every color, font and size comes from --v-* design tokens, written into
 * the page by the engine helper from the theme settings (see the Style book
 * page template for the full list). Styles live in cascade layers so that
 * Omeka core CSS, module CSS and an admin's custom CSS always override them.
 *
 * A theme's own stylesheet (its design) goes in the "theme" layer: after
 * the engine's layers, so it wins over them, and before the utilities.
