shop/doc/core-apps/features.md

• core-apps
  • shipped with the system, required for a functional shop
  • same mechanics as any other app (manifest.yaml, router, migrations, events, DI) — no special status in the loader
  • typically declared required: true in manifest so they cannot be switched off
  • distinct from custom-apps (optional / third-party, not shipped)
  • cover: auth, product catalog, cart, checkout, payment, orders, mail, shipment (planned), plus the AI layer (ai_core, ai_shop, ai_admin)
