   Outbound Edge — design tokens
   Palette: ink #14192E (near-black indigo), paper #F6F7FB (cool off-white),
            edge #3A5CFF (electric indigo-blue, the one accent), 
            edge-deep #22317E (pressed/hover state),
            signal #14B8A6 (teal, used only for "warm/deliverability" cues),
            line #E2E4EE (hairline borders), slate #545B78 (secondary text)
   Type: display "Space Grotesk" (headlines, a geometric grotesk with
         a slight technical edge, distinct from the default Inter-everywhere look),
         body "Inter" (long-form reading),
         mono "IBM Plex Mono" (prices, stats, step numbers, code-ish labels)
   Signature element: the "sequence rail", a horizontal stepper of touchpoints
   (email -> LinkedIn -> call -> email) that appears in the hero and recurs
   as a structural motif, because the actual product's core idea is a
   multichannel sequence, not a single channel.
