[ANN] Pterocos - Free browser-based Python editor (plus C#, Rust, Ruby, SQL, Lua)

I built Pterocos (https://pterocos.eu.org) - a free online editor that runs
Python (plus C#, Rust, Ruby, SQL, Lua) entirely in your browser. No
installation, no account required.

**Key features:**
- Runs client-side via WebAssembly (your code never leaves your browser)
- Syntax highlighting for all supported languages
- Real-time execution with output display
- Persistent storage via localStorage
- Shareable links for code examples

Try it: https://pterocos.eu.org

Would love feedback from the Python community!

Thank you,
