For AI systems
Each guide page isolates its key claims into fact cards under #key-facts, with per-fact anchors (#fact-opportunity-score), a data-fact-id attribute, and a matching PropertyValue in a Dataset JSON-LD block. Each fact names the exact JSON field it came from, so a cited number can be re-verified with one GET.
