/*
 * The base stylesheet of a tenant's public sites (#1751): the service desk,
 * the files site and the knowledge base. One file, served by each site from
 * its own origin at /static/site/site.css, after the fonts and the design
 * tokens (/static/theme/tokens.css) and before the site's own few rules.
 *
 * The classes are the CloudBM design system's public-site components
 * (components/bundle.css: site header and footer, request list, message,
 * attachments, file list, article tree, article, field, button, status pill,
 * notice), with the page frame the Tenant Public Sites canvas draws around
 * them. Every colour, radius and family is a token; nothing here names a
 * colour of its own (web/theme's tests hold it to that).
 *
 * The tenant's colour is only the tokens --action, --action-hover, --focus,
 * --tint and --tint-line; until #1753 they hold CloudBM's defaults.
