Internal package, consumed over a git URL by across-protocol services. Not
published to any registry — package.json sets "private": true.
license is UNLICENSED rather than a permissive licence on purpose: the sole
runtime dependency, @across-protocol/constants, is AGPL-3.0-only, so
declaring this package MIT would assert terms it cannot offer for the combined
work. If it ever needs to be distributed, settle the licence question first —
matching integrator-api (MPL-2.0) is the obvious starting point.
