feathericons/feather ? reverse-engineered prompt

Build me a simple open source icon set called Feather, with clean line style SVG icons on a 24 by 24 grid. I want the project to let people use the icons in three easy ways, in the browser with a script tag, in Node by requiring the package, and as an SVG sprite.

The browser version should replace any element with a data feather attribute with the matching SVG icon. The Node version should expose an icons object where each icon can be turned into an SVG string and accepts custom attributes like color, class, and stroke width. Please include a small example page and enough icons to make it feel like a real library, with consistent naming and simple documentation so someone can start using it right away.

If you need to check anything, look up the current docs online.
