- /sitemap.xml, from the API's /slugs plus the landing and listings: every address in every language, with hreflang and x-default. A 503 when the API is down, rather than a sitemap missing half the site. - /robots.txt, naming the sitemap on whatever domain this is served on. - Slugs renamed in the panel now redirect. The API has always kept the old address the moment one changed; middleware/redirects.ts answers it with a 301, from a list kept for a minute and through outages. - og:url, og:image (the record's own picture, the logo otherwise) and schema.org JSON-LD: Organization on the landing; WebPage, CreativeWork, Person or Service elsewhere. Shared through core/head. - The proxy-derived origin moves to core/origin.ts, used by the page shell, the landing and both server routes. In development only /api/* reaches Nitro, so the two files 404 under `npm start`; they were checked against a production build. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
