Structured data implementation

This site publishes JSON-LD describing the site identity, page roles, and visible breadcrumb hierarchy. The visible FAQ remains human-readable content; FAQ rich-result markup is not used because this site is not a government or health authority eligible for Google's FAQ rich result treatment.

Homepage: Organization, WebSite, and WebPage.
Guides and information pages: page-type markup plus visible BreadcrumbList.
Validation boundary: valid structured data may help search systems interpret page structure, but it does not guarantee display features, ranking, indexing, or AI citation.

Update and correction policy

Public price or policy changes should be supported by an official source or verifiable official checkout evidence.
Claims marked as estimates remain estimates until separately verified.
User feedback triggers review; it does not automatically alter published values.
No estimate should be interpreted as official billing advice or guaranteed savings.
