/*
    US History quiz (WEBUS-1762).

    Ported from the standalone design mock. Everything is scoped under .ve-quiz because the
    original stylesheet targeted bare body/header/main/footer selectors and applied a global
    *{margin:0;padding:0} reset, which would break the surrounding CMS page.

    Brand tokens are namespaced (--vq-*) so they cannot collide with existing site tokens.
    Fonts come from the page template - the mock's Google Fonts approximations are not loaded here.
