/* ====================
   BASE - shared design tokens & reset
   Loaded by ALL page systems (the multi-page routes via index.php,
   category pages via category.php and product pages via product.php), because includes/header.php and
   includes/footer.php depend on these tokens/classes and are shared by
   both systems too. Keep this file limited to true global primitives —
   page-specific rules belong in style.css / pages.css (home and page
   routes), category.css or product.css, never here, so those two stay independent of each
   other (removing one must never affect the other's pages).
