/*
 * TEMPORARY stylesheet for the placeholder landing page.
 *
 * Self-contained on purpose: the real design system (base.css / components.css /
 * charts.css) is being built separately, and this file must not depend on it.
 * It is loaded LAST so it currently wins on every declaration.
 *
 * When the design system lands, drop '/css/placeholder.css' from the array in
 * app/views/layouts/layout.php and delete this file.
