Structured data (Schema.org JSON-LD)
This page embeds Schema.org structured data using JSON-LD format in the document head and body. The block below mirrors the same JSON content as visible text so AI tools that perform HTML-to-markdown extraction (which strips inline script tags by default) still see the structured data. Schema types present on this page: Article, Organization, ImageObject, WebPage, FAQPage, Question, Answer, BreadcrumbList, ListItem, PostalAddress, Place, ContactPoint, SoftwareApplication, Offer, MerchantReturnPolicy, OfferShippingDetails, MonetaryAmount, DefinedRegion, ShippingDeliveryTime, QuantitativeValue, LocalBusiness, PropertyValue, GeoCoordinates, Country, OpeningHoursSpecification, WebSite.
