/**
 * BrainsOnBoard — Sources box
 *
 * Ships with the PLUGIN, enqueued only on posts that actually have a source
 * record. Same rule as the FAQ block and the table styling: markup generated by
 * the plugin brings its own CSS, so a template change can never orphan it.
 *
 * The box is the evidence trail for an article whose facts came from somewhere
 * else, so it is styled to be found rather than to be pretty — a rule above it,
 * a quiet heading, and numbered entries that stay legible at small sizes.
 *
 * The `.breakdance` prefixed duplicates are deliberate, for the same reason
 * they exist in bob-faq.css: Breakdance styles post content through two-class
 * selectors such as `.breakdance .bde-rich-text h3` (specificity 0,2,0), which
 * beat a single class (0,1,0).
 *
 * @package BrainsOnBoard
 * @since 2.2.0
