   product-detail-modern.css — Clean & minimal redesign for product-detail.php
   Loaded ONLY on product-detail.php, AFTER style.css + products.css + the
   inline <style>. Every selector is scoped to `body.product-detail-modern`
   so it overrides the legacy product-detail styling without bleeding to any
   other page. Matches home-modern.css design system.
