   page-default.css — khung giao diện cho template FALLBACK
   resources/views/pages/show.blade.php

   Đây là view dùng chung cho MỌI Page chưa có view riêng (nhóm
   quảng cáo/SEO/social/tiện ích). Nội dung là rich-text nhập tay
   qua CMS nên độ dài bất kỳ → khung phải đẹp cả khi content dài,
   ngắn, hoặc RỖNG. Prefix `pgd-` để không đụng post-detail (`pd-`)
   hay các trang khác.

   Chất kính theo liquid-glass-ui §1 (alpha .55–.74, blur 16–20px,
   saturate 155–160%, fallback @supports). Màu qua var(--site-primary…),
   COLOR LOCK 1 accent. Giao thoa nền fade về trắng (§4b).
