Day of Humanity - A Global Holiday for All

A clean, minimal one-page site with a full-width header image and sandy paper background presenting the "Manifesto for the Day of Humanity — March 21" (Purpose, Meaning, How It Is Celebrated, Date, Spirit), a Join section with Telegram link and downloadable calendar entry plus QR codes, rounded friendly buttons, Nunito typography, light blue accents (#3B82F6), and a small floating "counter" badge at the bottom-right.
