Content components: answer capsule & FAQ
All three sites independently converged on a front-loaded, AI-extractable answer block (AIComprehension on MarketInvoice, AnswerCapsule on FundBiz and PeptideClear), strong evidence it belongs in the standard. Their FAQ components do not agree with each other at all: MarketInvoice deliberately re-enabled FAQPage schema for Bing/Copilot, FundBiz's FAQ component still emits FAQPage despite the site's own documented "no FAQPage" rule (a real bug), and PeptideClear strips schema entirely by design. Read this one before writing the standard, it's a decision, not a default.
AIComprehension: collapsible direct-answer plus a two-column scope declaration ("this page covers / not covered here"). FAQ emits FAQPage schema, deliberately re-enabled for Bing/Copilot/Perplexity.
AnswerCapsule, componentised inconsistently across templates. FAQ also emits FAQPage, contradicting the site's own stated rule, a real bug, not a pattern to copy.
AnswerCapsule, two modes (definitional / summary). FAQAccordion emits zero schema by design, stripped fleet-wide per a documented directive after Google's deprecation.
