The solution is treating the Pages layer as a Composition Root — a concept from Clean Architecture — where features are instantiated and their interactions orchestrated. Features remain 'dumb' about global context, while pages act as directors connecting feature contracts via callbacks and events. This prevents 'God Features' (feature cannibalization) and enables substitutability: replacing an entire domain only requires changes in the pages layer. The hierarchy flows from app/ (global bootstrapping) → pages/ (orchestration) → features/ (domain logic) → shared/ (utilities), with communication always flowing vertically through the page, never directly between features. ## Full article daily.dev links to this article rather than hosting it.
