Notes

• Handles MTGGoldfish's IP-reputation layer automatically. Only the clean /sets/* surface is used — the /prices/* paths are blocked.
• For full-fleet scrapes, runtime is approximately 30–60 minutes at default concurrency. Memory: 512 MB.
• Foil cards are identified by a foil flag in the source data and are assigned to foil_price_usd rather than paper_price_usd.
