   این فایل پایه‌ی بصری *همه‌ی* صفحات وب است: صفحه‌ی معرفی (index.html)،
   پنل کاربری (base.html و همه‌ی صفحات داخلش) و صفحات مستقل (ورود، قوانین،
   پرداخت). رنگ‌ها هیچ‌جا هاردکد نیستن؛ همه از ۱۰ متغیر تم (--bg, --card,
   --border, --container, --buttons, --accent, --accent2, --text1..3) ساخته
   می‌شن که سمت سرور از پالت انتخابی کاربر (context_processors.theme_context)
   تزریق می‌شن - پس هر پالت روشن و حالت تیره خودکار روی کل سایت اعمال می‌شه
   و ورود از صفحه‌ی معرفی به پنل حس «یک سایت دیگه» نمی‌ده.
