Open this site through a local HTTP server. Double-clicking index.html does not start the application modules.
Open START-EXAM-TRAINER.cmd in this folder. It starts the site and opens your browser. Keep the launcher window open while using the trainer.
Once the server starts, open: http://127.0.0.1:5173.
For the source project, first run npm install and npm run build, or use npm run dev. A prepared build runs without installing npm packages.
