/* Document typography for rich-text content.
 *
 * Shared by the admin editor surface (what you see while writing) and the
 * public policy page (what visitors read), so both render a document the same
 * way. Every value comes from the design tokens, so the content follows
 * whichever theme the page uses. A page can tune the document through the
 * --rc-* properties instead of overriding individual rules.
 *
 * Only the tags and alignment classes the sanitizer allows are styled here
 * (services/rich_text.py): h2-h4, p, lists, blockquote, hr, links, tables and
 * the inline formats.
