/* Essentia Tech — shared site chrome.
   Fonts, color tokens, reset, and the header/footer partials all live here
   so they're defined once instead of once per page. Page-specific layout
   (hero, content columns, forms, etc.) stays in that page's own <style>
   block — this file only owns things every page shares.

   .shell-wrap is a fixed-width container used only inside <header> and
   <footer>, so the site chrome never resizes when navigating between pages
   with different content-column widths. Each page's own .wrap (defined in
   its own <style> block) controls its <main> content width independently. */
