/*
 * TukTukGO 翻訳機
 * WordPress固定ページへの組み込みを前提に、
 * クラス名は "tuktuk-translator-" で名前空間化しています。
 * グローバルなタグセレクタ（body, h1, p など）には直接スタイルを当てず、
 * 既存サイトのCSSを壊さないようにしています。
 *
 * デザイン方針:
 *   - 背景はほぼ白に近い薄いグレー（#F5F6F7）
 *   - カード・チャットバブルは白
 *   - 文字は濃いグレー
 *   - ブランドカラー（テール／コーラル）はボタン・アクセント・
 *     選択状態にのみ使用し、背景全面には使わない
 *   - 言語1（左側）＝テール、言語2（右側）＝コーラルで統一し、
 *     チップ／吹き出し／ボタンの対応が直感的に分かるようにする
