/* Optimised AI Limited — deliberately unlike the other sites: soft lilac-white and deep aubergine with a plum accent and an
   amber signal colour, a slab serif (Rockwell family) for headings over a plain sans, a left-aligned hero with a thick
   plum rule, square-cornered cards and a split dark band. No web fonts, so nothing loads off-site. */
