/* ============================================================
   株式会社大成工業 — トップページ意匠 (2026-07-28)
   ------------------------------------------------------------
   ・配色はロゴ原本から採寸した実際の色。紋章 #9F8124(真鍮金) /
     ワードマーク #080404。以前の試作にあった橙はブランド色では
     ないので使わない。
   ・見出しは明朝。ロゴの「株式会社大成工業」が明朝なので、
     そこから字面を連続させる。数字と英字だけ Oswald。
   ・使える実写は時津工場の3点だけ。写真で語れない分を
     タイポグラフィと線(＝配管)の動きで持たせる構成。
   ・比率は tools/taisei_build_images.py が焼いた値と対で持つ。
     どちらか片方だけ変えると必ず見切れる。
