   AKADEMIA CHMURKI — wygląd podręcznika, nie panelu SaaS.
   Granat jak papier nocą, serif w tytułach, jeden akcent (cyjan) i złoto tylko przy kredytach.
   Zero poświaty, zero gradientów w tekście. Obrazki lekcji robią robotę, CSS się nie wtrąca.
   3.09.2026 — przepisane po uwadze właściciela („bardzo mocny AI slop").
