   Cool minimal SaaS palette (Linear / Stripe / Vercel feel).
   Brand DNA (indigo + green) kept as accents only — body copy and
   most chrome are neutral so long-form pages read calmly.

     ink      #0a0a0a   (near-black, slight warmth)
     muted    #525252   (neutral grey)
     accent   #4338ca   (muted indigo — CTAs + links ONLY)
     complete #16a34a   (forest green — walked/completed payoff)
