   quiz.css — DataVix Quizzes module
   Matches the live landing page design system (https://www.datavix.in/landingpage/):
   warm off-white background, Inter body / Bricolage Grotesque display font,
   slate-900 pill buttons, white cards with slate-200 borders and soft large
   shadows, violet -> pink -> amber gradient accents. This file is
   self-contained (no dependency on the older style.css/landing.css used by
   /blog and /dashboard) so quiz pages render this exact design on their own.
   ============================================================ */

/* Since this file is self-contained (no style.css reset loaded on quiz
   pages), it must supply its own box-sizing reset — every width:100%
   input/card here assumes border-box, or padding pushes it past its
   container. */
