/*
 * devlog.css
 *
 * 「Shiha Project」テーマの配色（Ink #12151A / Sprout Green #6FA05A）を踏襲。
 * 既存テーマ側で --ink や --accent 等のCSSカスタムプロパティが
 * 既に定義済みの場合は、下記の変数値をそちらの名前に合わせて
 * 差し替えるか、いったんこのファイル冒頭の :root 定義を削除してください。
 *
 * 導入方法：
 * 1. このファイルをテーマフォルダ内（例：/assets/css/devlog.css）に配置
 * 2. functions.php で通常のCSS読み込みと同様に enqueue する
 *    例）
 *    wp_enqueue_style( 'shiha-devlog', get_template_directory_uri() . '/assets/css/devlog.css' );
