  A non-profit (ETS) pricing model: the paid tier exists to fund retention and support, not to meter the
  proof itself. Verification is free and unlimited at every tier, and the proof of existence never expires
  regardless of what is paid. Payment is processed by Stripe Checkout; no card data touches the Worker.
