Usage and overage
Usage is metered per team per month: media storage bytes, delivery bytes, and log storage bytes (logical, uncompressed). The dashboard Billing page shows all three against your plan caps, live.
Overage rates at launch (matching the market): storage $0.20/GB on Hobby, $0.10/GB on Pro/Network; delivery $4/TB on all paid plans. Overage is display-only in v1 — caps are enforced with errors (see Limits), nothing is billed silently.
