Assert the tracked teaser URL.
buildArticleFeed passes link to extractTeaser at Line [129] of nuxt/server/utils/articleFeed.ts. This test checks the item <link> and bare <guid>, but it does not check the <a href> in <description>. Add an assertion for the tracked teaser URL.
As per coding guidelines, nuxt/tests/**/*.spec.ts must maintain the enforced application coverage thresholds: effectively 100%, including 100% branch coverage, for covered app and server code.

Summary
Pre-release SEO pass, found by cross-referencing live GSC/GA4 data against the deployed site before cutting the sitemap-metadata + sponsor-click-tracking release. Mirrors gitlab.local MR !43.
sitemap.xml, every canonical tag, and every OG tag use the no-trailing-slash form, but that form 301-redirected to a trailing-slash URL (the one Netlify actually served 200 for) — meaning Google's sitemap-driven crawl hit a redirect on every single listed URL. The four legacy/articles/*redirects were worse: two hops ending in a client-side meta-refresh instead of one clean 301. Root cause: Nitro's directory-style (route/index.html) prerender output collided with Netlify's automatic trailing-slash normalization, which fired before this app's own_redirectsrules. Fixed vianitro.prerender.autoSubfolderIndex: false, verified against a realnuxt generatebuild and the full Playwright SEO suite.<title>About · stuar.tc · stuar.tc</title>in production right now — each page's ownuseSeoMeta({ title })already included "· stuar.tc", and the globaltitleTemplateappended it again.
