/*!
 * AF Base Stock — site.css
 *
 * site②「銘柄ジャーナル」子テーマのレイアウト・配色一式。
 * sample2/meigara-top.html を強く踏襲（新聞・金融マガジン調、
 * 明朝見出し ＋ 二重罫線 ＋ 赤のアクセント）。
 *
 * 親テーマ（af-*）の CSS は読み込み済み。ここでは以下を担当する：
 *   - デザイントークン（:root）
 *   - top-bar / masthead / market-bar / cat-nav（ヘッダー群）
 *   - wrap / sec-label / hero / grid-3 / grid-asym / mini-list / pull-quote
 *   - content-row / sidebar-block / cat-pill / ad-block
 *   - cta-strip / btn-red / site-footer（フッター群）
 *   - archive-header / page-header / page404 / post-nav / tag-cloud / pagination
 *   - レスポンシブ 960 / 640
 *
 * 記事本文（.entry-content 内）の装飾は entry-content-stock.css 側。
