Also, what's up with all the junk in readme? The project structure, random stats, tables. How bloating readme should help?

upd: Okay, there is a tiny disclaimer that the project is vibe-coded.

Not really a graphing calculator (although you can plot a bit) but is a proper old-school rpn scientific calculator with programming, numerical integration and solver, amazing complex number support etc, and has stood the test of time. All the things you would expect if you've used an HP-42 or similar.

Deploying a neo-vibey website for a calculator is a wild choice. On top of that, the first things (the buttons) dont work.

This does not spark the vibe I want. You either go full hacker-mode (and end up with a relatively nerdy website that is more about technicals and less about marketing), or you go full-on stakeholder-mode (you prioritize that your product is going to completely smash your competitor, making stakeholders feel FOMO).

I don't get it. At all.
