/* agt-chatbot.css — intentionally inert.
 *
 * The embeddable widget renders inside its own Shadow DOM. Its real
 * stylesheet ships inside agt-chatbot.js and is installed into the widget's
 * private shadow tree at runtime, so it cannot match any element of this
 * document. This file exists so the documented <link> keeps working and the
 * published URL keeps its text/css content type; it deliberately contains no
 * CSS rule, at-rule, @keyframes, @font-face, @property, or counter style,
 * because any of those could affect the host document simply by being
 * linked. Loading the widget requires only the <script> tag.
