/* NightShift AI: shared layout for every marketing page.
   Design tokens, base reset, site nav and footer. Page-specific styles stay
   in each page's <style> block (loaded after this file, so pages can override
   a token such as --max). Nav/footer markup lives in partials/ and is stamped
   into each page by scripts/sync-layout.mjs. */
