/* DzhetikSchool — styles from the brandbook.
   Palette: cherry #52000C, warm ivory #F1E5D7, noir black #1D1717, cherry red #810100.
   Type: headings — condensed grotesque (Heading Now; Oswald until the licence is sorted),
         text — Inter, accents — script (Bella Script CYR; Marck Script as a free stand-in).
   The one loud element: the display greeting with a script word over it, as on the brandbook slides.
   Everything else stays quiet so the data reads first. */
