/* ============================================================================
 * /certificates marketing page.
 *
 * Loaded automatically by the landing-light theme because the filename matches
 * the CMS page URL (see viewmodels/cms/cmspage_viewmodel._find_page_css), which
 * also guarantees it lands AFTER landing-cms-page-light-bulma.css. Several rules
 * below win on cascade order rather than specificity, so that ordering matters.
 *
 * Everything is scoped to .cert-page, which sits on each top-level <section>.
 * An unscoped rule here does not stay here: the landing-light theme is shared by
 * every CMS landing page, so a bare `p { }` would land on all of them. There is
 * a test for this in tests/test_certificates_page.py.
 *
 * The scope class is .cert-page and not .certificates because home-redesign.css
 * already owns a .certificates-section / .certificates-list family for the
 * homepage's certificate block. Those are different class names and would not
 * actually collide, but two similarly-named families on the same subject is how
 * an edit lands in the wrong file six months from now.
 *
 * TOKENS
 * This page uses --tp-* from b2b-tokens.css directly. team-trial.css carries a
 * --tt-* alias layer only because it predates the extraction; new pages skip it.
 * Adding a token means adding it to b2b-tokens.css, not here.
 *
 * The page is not a B2B page, but it consumes the same tokens, so the two
 * invariants that matter travel with it: every var() must resolve, and the
 * tokens must never arrive via @import. See the header of b2b-tokens.css for
 * why the second one is not a style preference.
 * ========================================================================= */
