/* =========================================================
   おかえりのいえ ― HERO と直下の3つの導線（hero.css / v5）
   ---------------------------------------------------------
   ・画面いっぱいの活動写真の上に、キャッチコピーを重ねるHERO。
   ・写真全体は暗くせず、文字の下だけにやわらかい影（veil）を敷いて可読性を確保。
   ・3つの導線は、写真の下端に重なる「タブ」としてHEROと一体化。
     配色はおかえりのいえのグリーン・アイボリー。
   ・base.css の旧HERO（写真4枚グリッド・暗いグラデーション）の指定は、
     このファイルで打ち消しています（base.css は変更していません）。
