     Ink          #0A0A0A   text, rules, dark chrome
     Asaan Green  #7AB82B   primary CTA, focus, active, emphasis
     Cream        #F6F4EF   page canvas / light surfaces

   Those three hex values are the only solid colours in this file. Every other
   value is a transparent tint of one of them, e.g. rgba(10,10,10,.13) or
   rgba(122,184,43,.14). No white, no sky blue, no indigo, no neon.

   Surface ladder, built from the tints alone:
     canvas  = Cream + 4% Ink wash + soft green bloom   (body)
     raised  = Cream                                     (.card, .panel)
     well    = Cream + 5.5% Ink                          (inputs, .item, .doc)
     action  = 8% Asaan Green                            (.toolbar)
     active  = 14–22% Asaan Green + solid green spine    (.item.active, .pill.firm)

   Cream-first light product UI — deliberately not dark mode. Mobile is the
   primary target (design width 375px).
