main/services/structured-page
Reads a book's information from the page of a bookshop or database site (BDfugue, Nautiljon) through the standard metadata those pages embed for search engines and link previews: the schema.org JSON-LD blocks, then the Open Graph <meta> tags. Neither site has a public API, and this avoids depending on their markup, which changes more often than those conventions.
