/**
 * Everything this app is handed, from a binding or from the environment.
 *
 * Two things here arrive one of two ways, and neither is a special case.
 * `HYPERDRIVE` carries a connection string on a platform that pools
 * connections for us, and `DATABASE_URL` says the same thing where nothing
 * does. An `AUTH` binding is a route to the issuer that skips the internet,
 * and `AUTH_INTERNAL_URL` is that route written out. Each pair is two
 * spellings of one fact rather than two deployments, which is why nothing
 * below branches on the runtime it is under.
 *
 * `AUTH_ISSUER_URL` is not part of either pair. It is the issuer's public
 * *name*, it is required, and it is the same value however the issuer is
 * reached — because it is what every token's `iss` claim is checked against.
