   যা বদলাতে পারেন (এই ফাইলের শুরুতে "TUNE HERE" দেখুন):

     --accent      মূল রঙ (ring, bar, আজকের দিন — সব একসাথে)
     --accent-2    রঙের হালকা সাথী (gradient-এর শেষ)
     --ring-size   গোল বড়/ছোট
     --bar-h       weekly বার মোটা/পাতলা
     --day-h       দিনের বক্স উচ্চতা
     --day-gap     দিনের বক্সের ফাঁক

   রঙ বদলানোর সহজ উপায়: <body data-accent="gold"> এর মধ্যে
   gold / ocean / forest / plum / slate / terracotta লিখুন।
   অথবা উপরের "Accent" ড্রপডাউন ব্যবহার করুন।
