/**
 * WP Answers Plugin - フロントスタイル
 * Q&Aページ + [wpa_commented_posts] ショートコード用
 *
 * 設計方針 (v3.0 - 完全マージ版):
 *   - 本CSSは Q&A レイアウト固有 + .wpa-cp-* 系（[wpa_commented_posts]）のみ
 *   - スレッドコメントUIと .wtc-cp-* 系（[wtc_commented_posts]）は wtc-style.css が担う
 *     （関心の分離 / 副作用領域の分離）
 *   - テーマの <h1>/<h2> スタイル干渉を避けるため、セクション見出しは
 *     <div role="heading" aria-level="N"> を使用
 *   - オレンジ(#ff6b35) はアクセント (PROバッジ/フォーカス) のみに使用
 *   - 構造的な装飾は淡いグレー (#e5e7eb / #f3f4f6 / #6b7280) を主軸に
