How to run in Vs Code environment

 Here is a clean Compose-View–friendly blog page (NO HTML tags, NO Prism, NO scripts).

You can copy & paste directly into Blogger → Compose View.

I’ve written it specifically for undergraduate students, using VS Code, with module filenames, terminal commands, and step-by-step run instructions.
