<h1>Gibble Lisp Bootstrap</h1>
<pre id="log">
This is the in-browser version of the bootstrap process; it operates
no differently than when invoked from the command-line, and has the
benefit of being able to be run without any further dependencies
(CLI requires Node.js, which is a hefty dependency.)
You do need a browser that supports ECMAScript 2015 or later, though.
Seeing as how it is rather rude to begin hammering your CPU when you
first load a page (as virtually every site you visit does now-a-days),
I'll wait for you to click the button below to get started.

<button id="start">| ... just a sec ... |</button>

All of Gibble requires JavaScript, actually.
