   المرجع: docs/DESIGN.md. يُبنى فوق css/ui.css (الحقول .input و.field-label،
   الأزرار .btn، المفتاح .switch، الحبوب .pill، القائمة .item) ولا يعيد تعريفها.

   الحركة: transform وopacity وحدهما، ودخول بـfill-mode backwards (لا transform
   يبقى بعد الانتهاء). الحلقات اللانهائية (الدوّار ومؤشّر الكتابة) تُلغى كلياً
   مع تقليل الحركة: مدة 1ms لحلقة لا نهائية تعيد الرسم إلى الأبد.
