 * site.css — Xitagaki service site renewal 2026
 *
 * 紫に寄せた黒をベースに、青 × 紫をアクセントにする。
 * 色はコーポレートサイト（wizoutworks.com）に近いので、黒を紫に寄せ、
 * フォント・ボタンの形・ヘッダー・レイアウト・CTA・フッターを変えて見分けがつくようにしている。
 *
 * 色は rgb(var(--accent) / .12) のように RGB の値を変数で持ち、透明度だけ変えて使う。
 * 動き：操作しなくても動き続けるもの（グラデーションの流れ・背景のゆっくりしたズームなど）と、
 * 画面に入ったときに一度だけ動くもの（.is-in が付いたとき）がある。
 * 動きを減らす設定（prefers-reduced-motion）のときは、すべて止めて完成形を見せる。
