/*
 * The one design language for custom pages: every page served outside the
 * Django admin, such as /analytics/ and the Stripe checkout harness.
 *
 * Tokens first, then components. Pages style themselves with these classes
 * and variables only; a colour or spacing value written anywhere below the
 * token block is a token that has not been named yet.
 *
 * The tokens are the mobile app's dark theme, copied from
 * app_flutter/lib/colors.dart (`WilmaColors` and `_buildDarkTheme`), so the
 * web pages and the app read as one product. When the app's palette moves,
 * move these with it; the comment on each names its source.
