 [`scripts/check-site.mjs`](../scripts/check-site.mjs) runs next and fails the build when an internal link, a `#fragment`, a sitemap URL or an `llms.txt` URL does not resolve (it applies the `vercel.json` redirects and rewrites), when JSON-LD does not parse or carries HTML entities, when an indexed page other than `/terms`, `/privacy`, and `/expocit/sources` lacks its question H2 (`#short-answer`) as the first H2, when a page's first heading is not its H1 or a heading skips a level (H1 to H3), or when an image has no alt text, a button has no name or a form field has no label.
 
-The guide pages in `public/<slug>/index.html` are generated, not hand-edited: run `python3 scripts/generate_seo_content.py` and commit its output. Short pages live in its `PAGES` list; pages with long-form copy, their own highlight-card descriptions, and their own FAQs (which also feed the page's FAQPage JSON-LD) live in [`scripts/seo_guides.py`](../scripts/seo_guides.py). Keep `PAGES` in order, because each page's related-guide links are picked by position. A guide entry can set a later `modified` date for that page alone; no page is dated earlier than `CONTENT_DATE`, which covers the copy every guide shares. Sections hold paragraphs and `h3`, `steps`, `list`, `table` and `example` blocks; paragraphs, list items and table cells can hold Markdown-style links to a site path or, for a primary source, an `https://` URL. Pages that show the shared `FAQS` are dated no earlier than `FAQS_DATE`, so move it when those questions change.

Every guide needs FAQs of its own in `seo_guides.py`; the generator refuses a page without them, so no two pages share boilerplate questions. [`src/test/seo/guide-content.test.ts`](../src/test/seo/guide-content.test.ts) fails when a guide has fewer than 700 words outside its related and About blocks, or when a sentence longer than 60 characters appears on more than three guides.
 
 Every guide opens with the reader's main question as its first H2 and an answer of at most 100 words, kept in [`scripts/seo_answers.py`](../scripts/seo_answers.py); the generator refuses a page without one or with a longer answer. Each guide shows visible "Published" and "Updated" dates (`PUBLISHED_DATE` or a `published` key, and the `modified` date) that match its Article JSON-LD. Prices and plan facts are stated "as of" the month in `factsCheckedOn` in `src/config/site.json`; move that date when you recheck them, and the pricing page's About block, `llms.txt` and the landing page follow. Every other guide has a one-line About that links to the landing page and pricing instead of repeating the plan facts. Copy in `seo_guides.py` and `seo_answers.py` that names the month itself (prices and competitor facts) needs the same edit: search those files for "As of". The generator also writes `public/llms.txt`, the plain summary for AI agents. `public/robots.txt` allows AI crawlers by name in their own group, which repeats the private-route rules because a crawler that matches a named group ignores `*`.
