 * মারকি-গোল্ড আলো, আর প্রতিটি পারসোনার নিজস্ব রঙে একটা "প্রেজেন্স-লাইট"
 * (breathing glow) যা কথা বলার সময় নিঃশ্বাসের মতো স্পন্দিত হয়।
 *
 * টোকেন সিস্টেম:
 *   রঙ      → নিচে :root-এ নামকরণ করা
 *   টাইপ    → Baloo Da 2 (ডিসপ্লে, ব্যক্তিত্বপূর্ণ) + Hind Siliguri (বডি, স্ক্রিন-লিজিবল)
 *   লেআউট   → মোবাইলে একক-কলাম স্ট্যাক, ≥1000px-এ ভিডিও+চ্যাট পাশাপাশি
 *   সিগনেচার → পারসোনা অ্যাভাটারের "breathing" আলো + মুড-রঙা অ্যাম্বিয়েন্ট আভা
