/* ==========================================================================
   Caietul de BAC: „caietele colorate”.
   Fiecare materie are coperta ei de caiet, în culoare plină, cu eticheta albă
   și liniatura hârtiei: pătrățele la matematică și informatică, dictando la
   română. Galbenul de marker marchează ce contează azi. Fără gradienți, blur
   sau umbre decorative; adâncimea vine din straturi de hârtie.
   Spațiere: 4 · 8 · 12 · 16 · 20 · 24 · 32 · 48.
