- Lógica de negócio em métodos do model ou em `services.py` por app.
- Views finas, só orquestram (autenticar, validar, chamar service, renderizar).
- `select_related`/`prefetch_related` em **toda** query com relação.
- Managers customizados pra query reutilizada.
- Forms ou DRF serializers pra validação, nunca no view.
- Sinais (`post_save`, etc) com moderação — escondem fluxo.
