/* ============================================================================
   ch-085 — «چالش‌های عملی» تست‌کاو (/challenges/)
   همان زبان بصری صفحهٔ /business/ (business.css): شب نیلی با ستاره، برنج کم‌رنگ، «پلاک» با چهار گوشه‌نمای حکاکی‌شده،
   و فیروزه به‌عنوان رنگ امضای چالش (همان رنگ بخش چالش صفحهٔ اصلی). فونت «راوی» برای همهٔ متن و تیترها
   (statics/fonts/site/RaviVF.woff2؛ همان نام خانوادهٔ فونت سراسری سایت، پس دو بار بارگذاری نمی‌شود).
   هر بخش یک تصویرسازی از خودِ چالش دارد و متن کم است. فضای نام: chx — هیچ قاعده‌ای بیرون از ‎.chx‎ نیست.
   صفحه همیشه تیره است. حرکت‌ها: challenges.js (کنسول) و ‎@starting-style‎؛ با «کاهش حرکت» همه‌چیز ثابت و کامل است.
   قالب‌ها: templates/site_pages/challenges.html، _challenge_icon.html
