/**
 * Whatsapp-Chat — front-end styles.
 *
 * Every selector is namespaced with `.whatsapp-chat` so the plugin can never
 * leak into (or be affected by) the host theme. Appearance is exposed through
 * CSS custom properties, so any project can rebrand it from its own stylesheet
 * without editing the plugin, for example:
 *
 *   .whatsapp-chat {
 *       --whatsapp-chat-color: #128c7e;
 *       --whatsapp-chat-size: 4rem;
 *       --whatsapp-chat-offset: 2rem;
 *   }
