/* ===== Brand Loader =====
 * Shared by the pre-React boot splash in index.html (#splash) and the React
 * <BrandLoader> component, so the hand-off from the static splash to the React
 * loader is seamless (identical markup + styles). Plain CSS (not MUI/makeStyles)
 * so it is available on the very first paint, before the JS bundle runs.
