aziemp66/saldo-learning-hub — reverse-engineered prompt

Build me a simple project called Saldo Learning Hub. I want it to work like a small learning platform backend where someone can create an account, sign in, browse courses or lessons, open a lesson, and have their progress saved. Keep it practical and easy to run locally, with a clean API, basic validation, sensible error responses, and some sample learning content so I can test it right away without extra setup.

This repo already looks like a Go workspace, so keep it in Go and organize it in a clean way that could grow into multiple services later. Please add whatever config, local run flow, and deployment ready setup make sense so it feels like a real working project instead of just empty folders. If there is no clear product spec in the repo, make reasonable choices, keep the scope small, and focus on a usable first version. You can look up current docs online if you need to.
