   `updataTime` types remain number for realtime and string for official.
   Redis locks prevent duplicate work across workers. Realtime region pages stay
   8 seconds apart. Failures retain the last successful data for up to 24 hours.

 - Realtime selects rows 4–10 (slice `[3:10]`), converts each original unit price
   with `1 / Price`, then averages those ratios in 万金币/元. Rounding to 2 decimals
   happens only after averaging; prices are not rounded before conversion. A new
