 *
 *  COLORS — edit the :root block below:
 *    --white, --off-white     → page backgrounds
 *    --grey-100 … --grey-500  → borders, muted text
 *    --black                  → buttons, headings
 *    --chrome-liquid          → silver “liquid chrome” accents (gradient)
 *
 *  FONTS — edit these variables, then update the Google Fonts <link>
 *  in each HTML file (index.html, work.html, etc.):
 *    --font-display  → headlines (currently Syne)
 *    --font-body     → body copy (currently Inter)
 *    --font-cjk      → Korean / Japanese / Thai (Noto Sans family)
 *
 *  SPACING — work/portfolio section:
 *    --section-pad, .work-gallery, .portfolio-meta (search “Work / Portfolio”)
 *
 *  LOGO IMAGE — .logo-img height is in the Navigation section
