// Barrel for the federation route subsystem.
//
// The implementation was split out of a single 7.6k-line file into cohesive
// modules under ./federation/. This barrel preserves the original public import
// surface (every `from '.../routes/federation.js'` import resolves unchanged) and
// composes the HTTP route registrars into `federationRoutes()`.
//
// See docs/systems/federation.md and
// docs/superpowers/specs/2026-07-10-federation-ts-split-design.md.
