Content and media
The CMS is in the core: pages, navigation, localized entries and content models, published separately from the catalog and invalidated in your frontend.
Pages and navigation
Editorial pages, menus and redirects per Store and locale.
Content models
Define your own entry types with fields, references and validation, then author against them.
Media library
Uploads go straight to S3-compatible storage; the core keeps the metadata and the variants.
Cache invalidation
Publishing tells your frontend which paths changed, so a CDN can cache aggressively.
