/*
 * portal-ui.css — the new Invenio portal's look (edoardo-hash/invenio-portal, src/app/globals.css +
 * (portal)/layout.tsx), copied for invenio.tools (Edo, 21 Oct 2026: "same UI and UX as the new portal").
 * Copy and adapt, never import: the two repos stay separate. Keep the tokens in step with the portal by hand.
 *
 * Every page loads this file and /portal-shell.js, which draws the header and the side nav.
 * Classes are prefixed `pu-` so they never collide with a page's own CSS.
