+2. `internal/pkg/service`

+   - It is responsible for initializing all **context** functionalities so that they are ready for use, as well as for **“mapping”** certain values to centralize all imports required for **presentations** in a single place.
+
+3. `internal/app/(presentations)`
+
+   - These **applications** will be used as **presentations** in order to serve the functionalities to an end user.
