/* ============================================================
   genikai2026 design system (2026-09-23, direction v2).
   Bold minimalist type on solid paper and solid ink. Hierarchy comes from
   size, weight and space: no eyebrow labels, no dots, no pills, no boxed
   cards, no icon rows. One faint gradient wash on the hero, nothing else.
   Navigation is a fixed left rail; "Menu" opens a full-height ink panel and
   the page folds sideways to make room. No em-dashes anywhere in copy.
