   Palette: deep emerald + royal navy (authority) / sky + mint (openness)
            / warm gold (premium accent, used sparingly)
   Type: Space Grotesk (display) + Inter (body) + DM Mono (data/labels)
   Signature: a single continuous "growth line" — an infinity path that
   runs the length of the page and animates through the hero — echoing
   "grow infinitely" without resorting to numbered-step clichés.
