/*
 * Research Report Design System — Public CSS variable contract
 * ----------------------------------------------------------------------------
 * Used by:
 *   - equity-research-report skill         (e.g. /YYYY/MM/DD/<ticker>-research/)
 *   - will-discord-analysis-report-to-page (Discord research → HTML)
 *   - daily-macro-strategy-briefing        (/YYYY/MM/DD/daily-macro-strategy-briefing/)
 *
 * Visual identity: "newspaper print" — cream paper, ink-on-paper typography,
 * sharp 2px corners, left-border accents, double rules. No rounded cards,
 * no hover-lift effects.
 *
 * Usage from a page:
 *   <link rel="stylesheet" href="/assets/css/research-report.css">
 *   Optionally override variables in a tiny inline <style>:
 *     :root { --accent: #1a4d2e; }   (e.g. green for bullish-only briefing)
 *
 * ----------------------------------------------------------------------------
 * EXPOSED CSS CUSTOM PROPERTIES (override these per article)
 * ----------------------------------------------------------------------------
