Hanami backend

Hanami's Ktor backend provides the internal API used by the SvelteKit application and the public course settings API. It handles authentication, course configuration, submission access, feedback documents, grading workflows, templates, and manual grade delivery for courses hosted on A+.

The code is organized by feature. This reference covers the public service boundaries and domain contracts used within Hanami. Transport wiring, database implementation details, and raw A+ response models are kept internal.
