// [npmjs.com/package/shortid](https://www.npmjs.com/package/shortid)
// shortid is a short, non-sequential, url-friendly, unique id generator

import shortid from 'shortid'; // ### classNames

/**
 * The brand band provides theming capability that adds personality and improves information density and contrast.
 *
 * NOTE: you may find that themes other than 'default' fail to load the appropriate styling in your application.
 * If this occurs the cause is very likely to be CSP settings on the server hosting your application protecting against style injections.
 * Changing these settings is not recommended. Instead, add the following styles to any stylesheet provided by the server itself (such as an external stylesheet):
 *
 * When using 'lightning-theme':
 * .slds-brand-band.dsr-brand-band_lightning-blue:before {
 *     background-image: url(/assets/images/themes/oneSalesforce/banner-brand-default.png), linear-gradient(to top, rgba(175, 197, 222, 0) 0, #1B5F9E);
 * }
 * .slds-brand-band.dsr-brand-band_lightning-blue:after {
 *     background-image: linear-gradient(to bottom, rgba(175, 197, 222, 0) 60%, #AFC5DE);
 * }
 *
 * For more information on the problem, [see this Stack Overflow question](https://stackoverflow.com/questions/17766817/refused-to-apply-inline-style-because-it-violates-the-following-content-security)
