/* eagraiclainne website — shared styles. Extracted from docs/design-plan.html
   (the frozen spec); tokens and rules are the design-plan's, applied.

   Mark colours use the app's canonical names (--mark-red … --mark-grey,
   matching web/src/theme/themes.css) rather than the design-plan's symbol
   aliases (--mark-fox …) — one scheme site-wide, since assets/css/app-themes.css
   and demo/demo.css are verbatim app copies using the colour names.

   Canonical header/footer markup (duplicate per page, greps must match):

   <header class="site band">
     <div class="wrap">
       <nav class="topnav" aria-label="Site">
         <a class="wordmark" href="{root}">eagraiclainne</a>
         <a href="{root}demo/">Demo</a>
         <a href="{root}compare/">Compare</a>
         <a href="{root}docs/">Docs</a>
       </nav>
       ...page hero/heading...
     </div>
   </header>

   <footer class="site band">
     <div class="wrap">
       <nav aria-label="Footer"><a href="{root}docs/">Docs</a> · <a href="{root}demo/">Demo</a> · <a href="{root}compare/">Compare</a> · <a href="{root}docs/install.html">Install</a></nav>
       <p class="soft">No cookies. No analytics. No external requests.</p>
