/*
 * K-Content theme: light lavender cards under a purple > pink > orange header.
 *
 * Everything lives under the wrapper class `.kc`, so it cannot leak into the
 * dark site chrome. Used by blog posts with `theme: kcontent` (the blog adds the
 * wrapper) and meant for reuse on the Dev Plans feature tab.
 *
 *   <div class="kc">                      block embedded in a page (centered, max 980px)
 *   <div class="kc kc-page">              whole-page variant (full width, children centered)
 *
 * Markup, inside the wrapper:
 *   header.kc-header > p.kc-title + p.kc-lead + .kc-date
 *   section.kc-section > h2.kc-section-title + .kc-card*
 *   .kc-card > .kc-tag + h3 + p* + .kc-highlight
 *   footer.kc-footer
 *
 * No CSS imports and no web fonts: only the system font stack below.
