/* ============================================================
   First Author — masterclass landing page

   The page alternates between two grounds, like a printed
   journal that switches to plates: INK bands carry the drama
   (hero, the paper, the price), PAPER bands carry the reading
   (stats, curriculum, FAQ). Every band re-declares the same
   token names, so components never know which ground they sit on.
