/* ============================================================
   bootstrap-lite.css — Bootstrap 3-এর ক্লাস-ভোকাবুলারি (.row/.col-*, .btn,
   .panel, .table, .form-control/.form-group/.input-group, .alert,
   .label/.badge, .checkbox/.radio) হুবহু বজায় রেখে, আধুনিক flexbox দিয়ে
   নতুন করে লেখা — কোনো টেমপ্লেট বদলাতে হয়নি। প্রকৃত Bootstrap সোর্স কপি
   না, নিজস্ব হালকা রিইমপ্লিমেন্টেশন, itiedu-এর teal/gold ব্র্যান্ড ভাষায়।
   ব্রেকপয়েন্ট Bootstrap 3-এরই মতো রাখা হয়েছে (768/992/1200px) যেন
   বিদ্যমান পেজের রেসপনসিভ আচরণ না বদলায়। ব্যবহৃত হয়নি এমন কম্পোনেন্ট
   (nav-tabs, dropdown, well, pagination, breadcrumb, carousel, modal)
   ইচ্ছাকৃতভাবে পুনর্নির্মাণ করা হয়নি।
