   accent can't carry dark text at full strength. Rather than switch the
   whole hero to white text (which would then fail against the *white* top),
   the transition is pushed late (70%) so the actual text content — which
   sits in the upper-middle of the section — stays on white/near-white; only
   the lower padding and the tail of the CTA row reach the true accent
   color. Verified by rendering, not just computed. */
