/* ============================================================
   NE✕ARA identity — the blog posts' one stylesheet.
   Static posts under /blog/*.html load this instead of their old inline
   <style> blocks. Tokens mirror app/nx.css; header/footer rules mirror
   components/nx/header.css and footer.css. Element-first: the 46 posts were
   written on ~20 different skeletons, so the type ramp lives on h1/h2/p/pre/
   table and the class rules below only cover the blocks those skeletons add.
   No gradients, no glow, one accent.
