   فقط متغیرها بازنویسی می‌شوند، نه خود قواعد — چون کل شیوه‌نامه از
   همین متغیرها استفاده می‌کند، تغییر تم به یک بلوک محدود می‌ماند.

   رنگ‌ها طوری انتخاب شده‌اند که نسبت کنتراست متن روی پس‌زمینه بالای
   ۴.۵ به ۱ بماند (استاندارد WCAG AA) و متن برای خواندن طولانی آزاردهنده
   نباشد؛ به همین دلیل پس‌زمینه سفید خالص نیست.
