edaplayground/eda-playground ? reverse-engineered prompt

Build me a simple web app for EDA Playground, the free online IDE for SystemVerilog, Verilog, and VHDL.

I want a page where someone can paste code, pick a language, and have a clean place to run and view results. It should feel like a helpful browser based coding playground for hardware design, with a straightforward layout and easy access to documentation and examples.

Please make it polished, easy to use, and good for learning and quick testing. If you need current details on how the original site works, look up the docs online and match the main user experience as closely as you can.
