Category lists are discovered dynamically by Claude using live market data.
Each category refresh = 1 discovery + N pricing calls. Results are cached in shared Cloudflare KV storage — available to all users indefinitely until the ↻ Refresh button is pressed. Watchlisted cards are always preserved across refreshes.
