/* ---- Tokens -------------------------------------------------------------
   Chosen for a small-business buyer, not a tech-startup one: navy reads as
   the most broadly trusted color in financial/professional-services
   research (the thing they need to believe before paying a stranger);
   warm bone keeps it human instead of sterile-corporate; the CTA accent is
   pushed toward saturated amber-orange, the color most consistently shown
   to lift click-through on primary buttons (urgency + approachability
   without red's alarm cue); teal-green carries the "approved / go ahead"
   signal — doubles as the stamp-of-approval motif already in the product
   illustrations.
