/* ============================================================
 * rinka-exchange.css — かけら交換所（/exchange/）の見た目の磨き直し（2026-09-26・追加のみ）
 *
 * ・読み込みは inc/fansite.php（交換所ページだけ・rinka-world-2026.css のあと）。
 * ・中身（値段・景品・かけらの計算・保存キー）は rinka-bond.js のまま。ここは見た目だけ。
 * ・絵文字のかわりに assets/img/ui/*.webp（ゲーム共通アイコン）と、さくらのかけら（CSSの絵）。
 * ・小さい文字を濃く（白地で 4.5:1 以上）。景品カードは少し豪華に。
 * 撤収: このファイルの読み込み1か所を消すだけ。
