microssscopein/idwilayahdagri ? reverse-engineered prompt

Build me a simple app that lets people browse Indonesian wilayah data from a JSON file.

I want a clean interface where someone can search and filter places, then drill down from province to city or regency, district, and village if the data supports it. Make it easy to pick a region and see the full location details in a readable way. If you can, add quick search, sorting, and a nice mobile friendly layout so it’s easy to use on a phone too.

Please use the wilayah.json file as the main data source and wire everything up so it actually works, not just a mockup. If any details in the JSON are unclear, infer the structure sensibly and look up current docs online if you need to. I’d like the result to feel polished, simple, and useful for someone who just needs to find and view wilayah information fast.
