One dynamic route generating dozens of matchup pages per site. MarketInvoice's is the most engineered generator (caps at top-12 per cluster, computes sibling cross-links at build time). FundBiz's is the most self-consistent (one JS constant feeds the capsule, the table and the FAQ so they can never contradict each other). PeptideClear's is deliberately the leanest.
/compare/ page, computes 3 sibling matchups per page to avoid orphaning.
