   QuizTime Manager — Parent Portal (/account/)
   Derives strictly from the landing.css design system: flat grey-blue
   canvas, white bordered cards, serif display headings, square corners,
   navy as the only accent, no shadows and no ambient motion.
   Layout mirrors the macOS app: fixed left sidebar, swappable main panel.
