/* ==========================================================================
   About Us — page-scoped styles.
   ফিক্স নোট: আগের ভার্সনে `*`, `body`, `.container` — এই সিলেক্টরগুলো গ্লোবাল
   (আনস্কোপড) ছিল। এই CSS ফাইল header.php-তে সবচেয়ে শেষে লোড হয় (Bootstrap,
   header-v-01.css, footer-full.css — সবগুলোর পরে), তাই সেই গ্লোবাল রুলগুলো
   পুরো পেজের (হেডার/নেভবার/ফুটার সহ) margin-padding রিসেট করে দিচ্ছিল এবং
   Bootstrap-এর নিজস্ব responsive .container ভেঙে দিচ্ছিল — ফলে পুরো পেজের
   লেআউট এলোমেলো দেখাচ্ছিল। এখন সবকিছু .about-us-wrapper এর ভেতরে স্কোপড,
   তাই এই CSS শুধু এই পেজের কন্টেন্টেই প্রভাব ফেলে, সাইটের বাকি অংশে না।
