mivaecommerce/miva-merchant-lsk ? reverse-engineered prompt

Build me a Miva Merchant library and set of modules that help manage store data and admin tools from inside Miva.

I want it to include the main merchant side pieces, an admin area, and the runtime side so the store can use it both in the backend and on the storefront. It should support loading and saving data as JSON, handle AJAX requests cleanly, and include reusable pieces for things like attributes and images. If it makes sense, include simple templates and UI for both admin and runtime so someone can actually use it without wiring everything together by hand.

Keep it organized so the different parts work together as one installable package, and make sure it’s easy to extend later. If you need to check the latest Miva Merchant docs or examples online, go ahead and do that.
