fabriziotappero/flyback-conv ? reverse-engineered prompt

I want you to help me build a complete open source KiCad project for a compact 70W flyback power adapter, similar to the one described in this repository. Keep it focused on a practical AC to DC converter with a two layer PCB, a full schematic, BOM, and board layout that could actually be manufactured.

Please make the design feel like a real small charger project, with the important power parts, control ICs, transformer, rectification, protection, and the supporting components needed around them. Use the files in the repo as the starting point, and if you need to check current component details or datasheets online, go ahead and do that.

I also want the project to be organized so it is easy to review, with clear schematics, a sensible BOM, and finished Gerbers that match the board. If anything in the old design looks outdated or incomplete, clean it up and improve it while keeping the same overall goal of a high density flyback converter.
