/* ---------------------------------------------------------
   Portfolio — editorial variant
   Same structure/content as the base template, different
   visual language: emerald/ink palette, serif display type,
   squared cards instead of pill/circle shapes.
   Palette / spacing tokens live in :root so the whole theme
   can be restyled by editing this block alone.
