Architecture layers

Every SPLENT feature follows a layered architecture. Each layer has a clear responsibility.

Route (HTTP)  →  Service (logic)  →  Repository (data)  →  Model (DB)

• Blueprints. HTTP routing and asset serving
• Services. Business logic, no HTTP concerns
• Repositories. Database access, one per model
• Seeders. Initial and test data population

Each layer only talks to the one below it. Routes never touch the DB directly. Services never produce HTTP responses. Repositories never contain business rules.
