/*
 * Shared styles for the Budgetti site.
 *
 * Deliberately one small stylesheet with no framework and no web fonts: the
 * whole site is two pages that exist to satisfy App Store Connect's Privacy
 * Policy and Support URL fields. A build step would be more to maintain than
 * the thing it builds.
 *
 * The palette is the app's, so someone arriving from the App Store listing
 * recognises where they are.
