Simple CS2 Offline Aim Trainer

I want a lightweight, no-frills tool that launches alongside Counter-Strike 2 and lets me drill aim mechanics offline only. The idea is to keep everything strictly on a local server or practice map, so there is zero interference with online play or VAC-protected servers...
