/*
 * site-nav.css - the site-wide top navigation bar built by site-nav.js.
 *
 * Reuses the shared design tokens so it sits on the same palette as the footer
 * and carries no colour of its own. Requires shared/tokens.css.
 *
 * Layout is a flex row: the brand home on the left, an optional page slot in
 * the middle (a page's own title, meta line and buttons, moved in unchanged),
 * and the global item list on the right. The item for the current page renders
 * as plain muted text; a primary item (the survey call to action, shown only
 * when there is no profile yet) is an orange pill.
 *
 * Hard rule: zero em or en dashes anywhere in this file. Hyphens only.
