/*
 * iotc-desc — IoTCrazy product description stylesheet (standalone, shared by the storefront and the admin panel).
 *
 *   Usage:  <link rel="stylesheet" href=".../description.css">
 *           <div class="iotc-desc"> ...HTML from the Description editor... </div>
 *
 * Self-contained: no framework, no site fonts, no images. Every selector is scoped under .iotc-desc and every custom
 * property starts with --iotc-, so it cannot clash with the host page (and the host page's CSS reset cannot flatten it).
 * Safe to host on a CDN; the admin preview and the storefront load the very same file, so what you preview is what
 * customers see. To retheme, override the --iotc-* variables on .iotc-desc (or on a parent element).
 *
 * Repo copies (must stay byte-identical): storefront public/assets/css/description.css,
 * admin public/assets/css/description.css — check with `php scripts/check-description-css.php` in the admin repo.
