   whyuser-shell.css  —  nav, footer and page shell

   WHY THIS FILE EXISTS
   The site keeps its full layout CSS inline in each page's <style>
   block and layers assets/dark-theme.css on top to flip the tokens
   dark. dark-theme.css is an OVERRIDE layer: it defines no .wrap and
   no .nav-inner, so it cannot style a page on its own.

   Pages without that inline block — the three new pages and the seven
   converted legacy pages — need this shell in order to render at all.

   HOW IT WAS BUILT
   Extracted from BOTH of the homepage's <style> blocks with a brace-
   matching parser, in document order, so the cascade is preserved. The
   second block is minified and holds the base .nav, .nav-links, .wrap
   and .btn rules; an earlier pass missed it, which is why converted
   pages rendered in serif with an unsized logo and no nav spacing.

   Order is load-bearing. A base rule must stay ahead of the media
   query that overrides it — appending recovered rules to the end
   silently inverts that.

   LOAD ORDER — this exact sequence:
     1. whyuser-shell.css     shell layout (this file)
     2. whyuser-core.css      new page components
     3. dark-theme.css        token overrides, LAST so it wins
