Cosa cambia davvero
Le parti più importanti che ho aggiunto/modificato sono queste:


css

.primary-menu.primary-menu-init {
  display: flex;
  flex-direction: column;
  align-items: flex-end;
  justify-content: center;
  gap: 0;
  width: auto;
  margin-left: auto;
}

.header-level {
  width: 100%;
  display: flex;
  justify-content: flex-end;
}

.header-level-2 .menu-link {
  padding-top: 12px;
  padding-bottom: 22px;
}
