+-- Migration: Add date_online and shop_score columns to products table
+-- These fields are imported from production to improve newsletter recommendation accuracy:

+--   shop_score   = products.score in production (sales-based popularity score)
+--
+-- After running this migration, do a full (non-incremental) import to backfill:
