/* ---------------------------------------------------------------------------
   Shared site navigation — one identical nav across every page, regardless of
   which page stylesheet (landing.css or reset/theme/site.css) is loaded.
   Self-contained: its own literal palette with a prefers-color-scheme dark
   block, prefixed pnav-/secnav- class names so it never collides with the
   per-page nav rules. The homepage section sub-bar (secnav) is the page-scoped
   in-page jump strip; every other page renders only the global pnav bar.
