/* =====================================================================
   Slopely — appka inštruktora a verejné stránky rodiča.

   TRI REGISTRE, JEDNA PALETA (tokens.css):
   • .reg-parent  — rodič a dieťa: teplý, ilustrovaný, emotívny (pas, /info,
                    karta, certifikát). Vlajková loď, rodič to ukazuje ďalej.
   • .reg-field   — inštruktor na svahu: vysoký kontrast, veľké plochy,
                    žiadna dekorácia, ktorá kradne priestor.
   • .reg-admin   — majiteľ školy (admin.css): zdržanlivý, dátový, prémiový.

   Registre zdieľajú farby, typografiu a odsadenia. Líšia sa hustotou,
   zaoblením a mierou ilustrácie — nie vlastnou paletou.
