note: 'Most rate tables (Neptune Analytics m-NCU hourly prices, serverless NCU-hour, storage per GB-month,
  I/O per million requests, backup storage, data transfer tiers, workbench notebook instances) render
  as unresolved pricing template tokens in the captured text, so no numeric values are visible. Numeric
  figures visible are the $0.15 per vCPU-Hour CPU credit charge, the $0.01 per GB EC2 regional transfer
  note, and illustrative figures inside four worked pricing examples (e.g. $0.348 per hour db.r5.large),
  which are examples rather than the rate card. Billing is usage-based: on-demand instance hours, serverless
  NCUs, storage GB-month, I/O per million requests, plus optional 1-year Database Savings Plans.'
