   v12 — কাচ-নকশা ও রঙিন ওভারলে (সাইট + অ্যাডমিন)
   ---------------------------------------------------------------------
   ⚠ এটি app.css / ribbon.css / admin.css-এর **পরে** লোড হয় এবং কেবল
     যোগ করে বা ওপরে বসে — পুরনো ফাইল ছোঁয়া হয়নি। এই ফাইলটি না থাকলে
     পাতা পুরনো (কম রঙিন) চেহারায় ঠিকই চলে।

   ⚠ রঙ-নিয়ম অপরিবর্তিত: সতর্কতার রঙ (BMD শ্রেণি, US EPA ব্যান্ড) কেবল
     ডেটার অর্থ বোঝাতে। এখানকার গ্রেডিয়েন্ট ও সাজসজ্জার রঙ সেগুলো থেকে
     আলাদা — "লাল মানে বিপদ" কখনো ভাঙে না।

   ⚠ backdrop-filter কেবল সাজসজ্জা: না চললেও প্রতিটি কাচের পৃষ্ঠের নিচে
     যথেষ্ট অস্বচ্ছ রঙ আছে, তাই লেখা পড়া যায়।
