recipes.Extract(page, url) scans a page's application/ld+json scripts and og:site_name with a small targeted scanner (no new dependency) and returns the single Recipe node: top level, top-level array or @graph, @type as a string or array. It picks the largest image and resolves it against the page URL, flattens HowToStep/HowToSection instructions in order, converts ISO-8601 durations to minutes (total derived from prep + cook when absent), and names the site from publisher, og:site_name or host. No Recipe is ErrNoRecipe; two is ErrManyRecipes; shapes schema.org does not allow, such as a "20 minutes" cookTime, are ErrMalformedRecipe. testdata holds trimmed real pages from BBC Good Food, Budget Bytes, RecipeTin Eats (HowToSection), King Arthur Baking, Delish (top-level array), Food.com, Bon Appétit (non-ISO duration) and a Budget Bytes page with no Recipe.
