/*
 * Proofloop documentation
 * ---------------------------------------------------------------------------
 * One stylesheet, no build step, no remote request of any kind — no CDN, no
 * webfont, no analytics. The documentation has to open from a double-clicked
 * file on a laptop with no internet connection, which is how a buyer reads it
 * on the train before they start, and remote assets are an Envato auto-reject
 * besides.
 *
 * The token names mirror resources/css/app.css so the docs look like the
 * product. They are duplicated rather than imported because this file is
 * shipped as static HTML alongside the application, not compiled with it.
