/**
 * Pure post-processing for analyst markdown HTML output.
 * Takes the HTML string produced by marked.parse() and promotes ALL-CAPS-only
 * paragraphs to section-header divs, preserving the analyst prompt's SIGNAL /
 * THESIS / RISK / WATCH visual treatment.
 *
 * No DOM dependency — safe to import in Node.js test runners.
