/*
 * Skeleton for the product micro-sites under /projects/<app>/.
 *
 * Each product page paints itself in its app's own colours on top of this file:
 * it overrides the tokens below on `body.<xx>-page` and adds page-scoped styles.
 * The rest of the site uses /content.css. This file is frozen on purpose: the
 * product pages were drawn against these exact rules, so changing one here can
 * move every app page at once. Only the shared header is meant to change.
