 *
 * 【4列・gap 20px の場合】
 * ・1列の幅 = (100cqw - 60px) / 4
 * ・1行の高さ = 上記 × 9/16（16:9） = grid-auto-rows の値
 *
 * 【出る2パターンのサイズ】
 * ・小（1セル）: 幅 = 1列幅、高さ = 1行高さ
 *    例: 100cqw=536px → 約 119×67px → 画面で 123×69px 程度になることがある
 * ・大（横長=2列×2行）: 幅 = 2列 + 1gap、高さ = 2行 + 1gap
 *    例: 100cqw=536px → 幅 258、高さ 154 → 画面で 268×159px 程度になることがある
 *
 * 変更したい場合: gap / 列数 / 16:9 の比率を下記の calc で調整
 * 表示サイズ 1.5倍: 行高さに * 1.5 を適用
