/* KCA — the shell for pages that live outside the compiled bundle.
 *
 * gallery.html, blog.html, post.html and testimonials.html are plain HTML,
 * because the site itself is Vite output whose source tree is not in this
 * repository and cannot be added to. That makes matching its appearance a
 * copying job, so it is done once here rather than four times.
 *
 * The custom properties are the same triplets the bundle's stylesheet defines
 * (assets/index-*.css). Keeping the same names and the same values means a
 * future rebuild of the site can be matched by changing this block alone.
