bryllim/workout-guide ? reverse-engineered prompt

Build me a website and npm package for an open exercise illustration library.

I want a searchable gallery of workout moves, with a clean landing page, individual exercise pages, and a simple guide that shows how to use the package in real projects. Each exercise should have multiple frames so it can feel animated or step by step, and the library should let people look up exercises by name, search by body area or equipment, and get the image asset for a chosen frame.

Please make it feel polished and easy to browse, with all the exercise data and assets included in the project so it can be used offline too. The package should be framework neutral and easy to install, and the site should explain how to use it with code examples. If you need to check current docs for Astro or modern package setup, go ahead and look them up online.
