/* Intermediate widths (iPad portrait, laptops). Between 761px and 1400px the hero
   copy is already at its 760px max while the emblem still sits at the top-right,
   so the two collide. Send the emblem down behind the meta row and fade it instead
   of narrowing .hero__inner (that would break h1 into more lines).
   上限を1100→1400にした理由（2026-08-18・実測）：
   文字の実占有領域（Rangeの矩形）と絵の実効領域（薄い白板を除いた内側）で測ると、
   重なりは 1101px=44px / 1150px=63px / 1200px=82px で、1210px以降は+67pxの余白に転じる。
   ⚠️ この境界は h1 の折り返し点に乗っているだけで、10px広げると150px動く（1200→1210）。
   つまりフォントの読み込み状況や字形が変われば境界も動くので、1240px付近に合わせるのは危険。
   1401pxまで余裕を取って「絵を下へ逃がす」扱いを適用する。
   1401px以上は文字と絵が70px以上離れるので、従来どおり右上に大きく出す。 */
