## Description

favico.js is a JavaScript tool for managing browser tab icons, providing the ability to update favicons in real time and render dynamic media. It functions as a manager for updating icons and a generator that converts images, video, or webcam streams into browser tab visuals.

The project specifically provides a system for displaying notification badges and numeric counts over a favicon to alert users of new activity. These badges support custom text, configurable colors, and animations, with utilities to update or reset the counts as application state changes.

The library covers a range of dynamic rendering capabilities, including the integration of live webcam streams and real-time web alerts. It achieves these updates by sampling media frames and composing images to reflect changing application states directly in the browser UI.
