/* ============================================================
 * decor.css — 装飾（紅葉・バラ・立体フィギュア）と文字の登場演出
 *
 * 仕組み
 *  - HTML の <span data-decor="pumpkin|candle|ghost"> に、js/decor.js が
 *    assets/decor/*.svg をインライン展開する。見た目は ::after の立体フィギュア
 *    （*-figure.webp）で描き、SVG は透明にしてクリック範囲としてだけ使う。
 *  - 状態クラス（JS が付ける）
 *      pumpkin : .is-lit      … 明るくなる（hover / focus / tap）
 *      candle  : .is-flicker  … 光が強くなる（hover / focus / tap）
 *      ghost   : .is-visible  … 画面内に入ったらふわっと出現
 *  - SVG 内のクラス名 .pumpkin-eye .pumpkin-mouth .candle-flame .candle-glow .ghost-body は変更しない
 *
 * 守ること
 *  - 装飾は本文・ボタンに重ねない。pointer-events は装飾自身にのみ持たせる
 *  - reduced-motion 時は動かさない（base.css でも一括停止）
 * ============================================================ */
