Embedding p5js scripts in Grav page

Is it possible to embed a p5js sketch into a Grav page? (p5js is a version of the Processing language for Javascript). On a standard HTML page, I would use the following to display the p5js sketch:

<script src="p5.js"></script> 
<script src="fallingEnvelopes.js"></script>
<script src="envelope.js"></script>
<script src="envelopeSystem.js"></script>

p5.js is the library, and the other files make up my animated sketch. Is there a way to use this in Grav?

@dmeissner, There is... Take a look at the docs:

• Theme customisation
• Asset Manager

Thanks very much for getting back to me. My impression was that the Asset Manager related to customizing themes, while I'm just trying to create a few pages that display an animation as the main content of the page, not as a decoration. I'll keep going over the documentation, but maybe this would be possible by enabling Markdown Extra, and just adding the code directly on a page?
