/* Kernalite "joyful" site theme — shared by every page on kernalite.com.
 *
 * Dark slate ground (#0d1117), emerald brand (#10b981), and a cast of four
 * chibi guides (assets/chibi/*.svg) who introduce sections instead of
 * marketing headings doing all the work. Replaces the neo-brutalist layer
 * (assets/brutalist.css, kept as a one-line @import shim so pages published
 * before the switch keep resolving).
 *
 * Two contracts this file keeps so older per-page <style> blocks survive:
 *   1. The legacy custom-property names (--cream, --ink, --yellow, --pink,
 *      --cyan, --line, --hard-shadow, --bg-*, --text-*) are redefined here
 *      with joyful values. A page that says `background: var(--cream)` gets
 *      the slate ground; `var(--yellow)` is now the emerald accent.
 *   2. The class names the chrome injector (assets/joyful-chrome.js) and the
 *      shared components use (.bt-*, .site-card, .site-cta, .glass, .display)
 *      are unchanged.
 *
 * Chibi components (.chibi-stage, .speech-bubble, .feature-chibi-badge,
 * .kl-guide) live at the bottom. Zero framework, zero build step.
