OperStack Astro Starter is for content sites that have to rank in search, get quoted by answer engines and convert readers into leads.
Inside: five content collections (guides, entities, comparisons, projects, news) with typed frontmatter, an answer-first article layout with a quotable first paragraph, a facts table and a sources list, an entity layout with data cards, an honest sitemap with lastmod dates, generated llms.txt and llms-full.txt, IndexNow and Google Indexing scripts, twelve Cursor rules, and the fifteen OperStack gates (npx @operstack/gates) wired into the build so cut titles, copied paragraphs, hollow sections, dead links and unsourced figures never ship.
The demo is a complete fictional market, Isla Verde: six buyer guides, four district profiles, two comparisons, four project data cards and two news items, all passing every gate. Replace the market and keep the machinery. MIT licence, no telemetry, no account.
