   FUSION: HEXELLA DIVE — Social Hub  (/fusion-hexella-dive/links)

   Add-on a fhd-landing.css, mai un sostituto: quel file possiede i token, il
   reset e i primitivi condivisi (.fhd-shell, .fhd-btn, .fhd-link, .fhd-chip,
   .fhd-cut, .fhd-eyebrow, .fhd-footer...). Qui vive soltanto ciò che serve
   all'hub. Ogni regola resta sotto `.fhd-page`, esattamente come la landing,
   così questo foglio non può trapelare su homepage / legal / myZenkai.
