Usage accrues only while a Sailbox is running. Sleeping, paused,
checkpointing, and cold-starting time is not billed. Usage is measured every
second and added to your bill in one-minute increments.
Volume storage is billed separately for each hour the volume exists, even
when attached Sailboxes are sleeping, until it’s deleted.
