be5invis/Iosevka ? reverse-engineered prompt

Build me a customizable coding font project like Iosevka.

I want a font family I can use for code, terminals, and technical writing, with both monospace and slightly more proportional options. It should include several weights, widths, and italic styles, plus support for common programming symbols, ligatures, and a lot of Latin based languages. I also want a simple way to tweak character shapes and generate different font variants from the same source.

Make the project easy to build from the command line, and include clear docs for how someone can choose a version, generate their own build, and install the final font files on their computer. If there is a specimen or preview page, include that too so I can see what the fonts look like. If you need to look up current docs or best practices for font building, go ahead and check online first.
