   Nejadhari Private Limited — design tokens
   Concept : premium editorial — generous whitespace, a refined
             display serif set large, roman-numeral itemization
             in place of card grids, brand colour used sparingly
             (rules, small-caps labels, one CTA) rather than filled
             throughout.
   Color   : warm stone paper + graphite ink; navy #012e5f and
             green #4d8027 as restrained accents.
   Type    : Cormorant (display, incl. italic) + Jost (body / labels)
