Liverus/SCPSL-Internal — reverse-engineered prompt

Build me a harmless local demo based on this SCP Secret Laboratory internal cheat project, but make it only a learning sandbox and menu mockup. I want an ImGui style overlay window with tabs, toggles, sliders, keybind fields, and a config save and load flow that looks like a cheat menu, using fake player data and dummy values only.

Please do not make anything that injects into the game, bypasses anti cheat, reads game memory, changes gameplay, or works online. The goal is just to recreate the interface and project structure enough so I can learn how the menu, feature toggles, event handling, and config system would be organized in C++.

Include example fake features like ESP preview, FOV slider, speed value, chams color picker, and status text, but keep everything disconnected from any real game process. Make it easy to build and run as a standalone Windows demo. Look up current docs online if you need to.
