boringdesigners/boring-avatars ? reverse-engineered prompt

Build me a small React library that generates simple SVG avatar placeholders from a person’s name, email, or any random string.

I want it to work like this, I import one Avatar component and pass a name, then it renders a unique looking avatar every time for that input. Let it support a few different styles like marble, beam, pixel, sunset, ring, and bauhaus, plus options for size, square shape, and a custom color palette. The avatar should be lightweight, reusable, and easy to drop into any app.

Please make the defaults sensible, include a clean README with examples, and set it up so it can be installed from npm and used right away in a React project. If you need to check current docs or best practices for the build setup, look them up online.
