/* =====================================================================
   SmartSchool Uniform BD — Phase 18 (2026-10-14): পার্টনার স্কুলের লোগো-সারি + "About us" পাতা
   frontend/partials/school-logos.blade.php আর frontend/about.blade.php নিজেরাই এই ফাইল যোগ করে (@pushOnce('styles'))
   — শুধু হোম ও About পাতায় নামে।

   মালিকের চাওয়া: "about us page টা লাগবে আর front page and about us পেইজের মধ্যে আমরা যে সমস্ত school এর সাথে কাজ করছি
   তাদের logo গুলো দেখাবে নিচের দিকে, logo গুলো slider animation হতে থাকবে সব সময়"।
   ভাগ: ১ লোগো-সারি · ২ About পাতা · ৩ ছোট পর্দা · ৪ কম নড়াচড়া / ছাপা
   ===================================================================== */
