thererevocss/FORTNITE-MACROS-EDITOR-V2.5 ? reverse-engineered prompt

Build me a simple Windows desktop app that feels like a Fortnite Macros Editor 2.5. I want a clean, easy interface where someone can turn features on or off, tweak settings, and set custom hotkeys, with those hotkeys saved and loaded from a JSON file. Include the main actions shown in the project, like FOV, Tunnel, Retake, Double 90, Recoil Control, Prefire, Prefire Boost, Quick Edit, Reset Build, Layer Rush, Turtle, Crouch Spam, Clicker, Bunnyhop, Auto Build, and Fast Loot.

Please make it feel polished and straightforward, not overly technical. If there are language or resource files already in the repo, hook those up so the app actually uses them. I also want sensible defaults, clear labels, and basic validation so it does not feel broken if a setting is missing. Recreate the overall feel of the existing tool as closely as possible from the files in the repo, and look up any current docs online if you need to.
