   Tezos Ukraine case study — free-form section below the shared hero.
   Built on the same "interesting blocks + light parallax" language as the
   Forklog Consulting case, tuned to Tezos Ukraine's own bakery-on-blockchain
   brand: warm brown/orange gradients, a soft cream background, Roboto-style
   type samples — all still set in the site-wide font used everywhere else.
