/**
 * Skin Diseases shortcode layout
 *
 * Styles the curated common-disease buttons and the A–Z patient-article
 * list. Appearance (colours, type, outer chrome) is driven by `--sd-*`
 * custom properties on `.sd-diseases`. Defaults fall back to the theme
 * Zen palette (`--cc-*`) when present, then to the hex values below.
 * Grids, gaps, radii and breakpoints stay as layout — override tokens,
 * not those rules.
 *
 * Per-page restyle (Additional CSS, or a wrapping Gutenberg Group class):
 *
 *   .page-id-42 .sd-diseases {
 *     --sd-bg: transparent;
 *     --sd-padding: 0;
 *     --sd-max-width: none;
 *     --sd-color: #1a1a1a;
 *     --sd-font-size: 16px;
 *   }
 *
 * Tokens: --sd-bg, --sd-bg-alt, --sd-bg-surface, --sd-bg-hover,
 * --sd-color, --sd-color-accent, --sd-color-notice, --sd-border, --sd-divider,
 * --sd-font-family, --sd-font-size, --sd-font-size-title,
 * --sd-font-size-letter, --sd-padding, --sd-max-width.
 *
 * `.sd-diseases__nav` is reserved for a future A–Z filter.
 *
 * Enqueued on the topic mosaic, a topic list, /skin-diseases/{slug}/,
 * /skin-diseases/topic/{topic}/{slug}/, the matching /full/ routes, and
 * the generic /skin-diseases/full/{title}/ chapter route — see
 * diseases_enqueue() in inc/render.php.
