pa1n-dev/nixware_x64 — reverse-engineered prompt

Build me a harmless desktop demo that recreates the look and feel of the old Nixware style Garry's Mod menu as a visual showcase only. I want the same kind of tabs, settings panels, custom background support, and polished game style interface shown in the screenshots, but it must not hook into Garry's Mod, inject into any process, bypass OBS, automate aiming, or include any cheating behavior. Treat it like a fan made archive and clickable prototype that people can open to explore the design and flow.

Add realistic sample options, fake status info, and working toggles so the screens feel complete, plus simple save and load for local settings. Make it look clean and close to the original vibe, including the menu layout and general styling. Keep it standalone and safe to run on its own. Include short setup notes so I can open it locally without much hassle. If you need reference, check the public README and showcase images online.
