 * - TOP（is_front_page()）だけで読み込む（functions.php current_official_top_assets()）。
 * - すべての指定を body.current-top 配下に限定し、下層ページへ波及させない。
 * - 文言・構成・リンク・フォーム・計測のフック（data-*／class）は front-page.php のまま。
 * - 波：FB.png の右端（x=1250, y=0, 390×624）を切り出した assets/images/top/top-wave.webp。
 *   PC／タブレット：画面高の装飾レイヤーを右側に固定（幅26%、701〜1000pxは22%）。
 *   700px以下：ページ上端（top:0）から配置し、下側を透明へフェードして初画面内で終える。
