   The ivLis STUDIO design language (ivlis.kr): white pages, flat colours (no gradients), bold Pretendard type,
   Toss-style pills and bento cards, springy motion. One page holds four views: landing, create/edit, import
   and the card itself. Colours used for small text are the darker steps so everything passes WCAG AA.
