/*
 * تغییر ۲: انیمیشن کارت‌های پروژه
 *
 * مشکل قبلی: کارت‌ها با display:none/block کنترل می‌شدند.
 * display:none قابل transition نیست — به همین دلیل انیمیشن نداشت.
 *
 * راه‌حل جدید:
 * - hidden-card دیگر display:none نمی‌گذارد، بلکه با ترکیب
 *   max-height:0 + opacity:0 + overflow:hidden + margin-top منفی
 *   کارت را "پنهان" می‌کند و فضای آن را حذف می‌کند
 * - این روش کاملاً با CSS transition سازگار است
 * - JS هم دیگر style.display را دستکاری نمی‌کند
 *
 * چرا max-height به جای height؟
 * چون height:auto قابل transition نیست، اما max-height هست.
 * مقدار 600px بیش از حداکثر ارتفاع واقعی هر کارت است.
