   Marketing site rebuild — buyer-pool surfaces, methodology, chain coverage

   New use-case landing pages for AI training, funds & research, restaurant tech, operators, and developers. /methodology page goes public; /chains lists the top 25 publicly-traded restaurant tickers covered. Pricing page restructured around data_tier=primary gating and feature gates per tier. New SKU pages at /data and /license. Scale tier moved from $599 to $999/2M to align with wholesale-partner pricing economics.
