Pages are client-rendered → Firecrawl, 1 credit per item, capped by `maxItemsPerRun`. Alt Value is stored as a guide_value observation (confidence 0.6); recent transactions become sales attributed to Alt with the original listing URL in metadata (confidence 0.65 — second-hand aggregation); the Alt list price is a fixed-price listing.",
