/*
 * styles.css(お問い合わせフォーム用)
 * ---------------------------------------------------------------------------
 * ssgform/styles.css をベースに、サイト本体(src/styles/global.css)の
 * デザイントークン(--color-*, --font-*)をそのまま参照する形に置き換えたもの。
 * このファイル単体で色や書体を再定義せず、既存の値を使い回すことで、
 * サイトの配色を変えたときにフォームも自動的に追従するようにしている。
 *
 * すべてのセレクタを .ssgform-contact 配下に閉じ込めている点が元のファイルとの
 * 最大の違い(元のssgform/styles.cssは body や h1 など裸のタグにも
 * スタイルを当てる前提で作られており、サイト全体にそのまま読み込むと
 * ヘッダー・フッターなど他の要素まで巻き込んでしまうため)。
 * body全体のリセットや :focus-visible の輪郭線、prefers-reduced-motion
 * への対応はサイト側のglobal.cssに既にあるものをそのまま利用し、ここでは
 * 重複させていない。
