/* KikoWorks — shared base for every site page.
   Design tokens, fonts, reset, header, footer, and eyebrow labels.
   Linked first by: kikoworks.html, privacy.html, 404.html (with kikoworks.css),
   05_portfolio/portfolio.html (with portfolio.css), and the case pages (with case.css).
   Deploys to /base.css via build_site.sh. Fonts are self-hosted from fonts/ (OFL). */
