/* ============================================================
   The Discipline Advantage / Dan Case
   Design system — palette and type aligned with the book cover.

   Palette:
     - Cream background (warmer than off-white) matches cover
     - Deep navy primary (matches book title)
     - Warm gold accent (matches book accents)
     - Generous whitespace, restrained color use

   Typography:
     - Georgia for display + body (cohesive, serious, matches book)
     - System sans for UI labels and small metadata
     - Strong hierarchy through size + weight, not color

   Layout:
     - 1080px max content width
     - 8px base spacing unit
     - Mobile-first responsive
