/* =============================================================================
   PikaSim primary navigation (desktop bar + mobile slide-in).
   Redesign of the old hamburger-only side-nav. Uses the locked brand tokens from
   style.css :root (--color-primary #F7931A, --color-navy, --color-ink, slates).
   Desktop: horizontal bar with grouped dropdowns (hover + focus + click).
   Mobile (<=900px): a slide-in panel with the same groups as labelled sections.
