   Session: J-162 (TABLE-SERVICE-1)  ⚠️ MODIFIED — previously POS-DISCOUNT-3
   LastModified: 2026-09-30
   Module: M12 POS (Frontend) — full-screen POS shell styling
   ============================================================
   📝 J-162: شريط النوع أزرارٌ فعليّة · وسما «في المطبخ» و«لم يُرسَل» ·
     تذييلٌ بثلاثة أزرار · أزرار التذييل المعطّلة.
     والنسخة الخاملة Components/Pages/Pos/pos.css حُذفت فعلاً.
   ⚠️ MODIFIED FILE — Original from POS-Redesign
   📝 Changes (POS-DISCOUNT-3):
     - أنماط زرّ الخصم المُفعَّل + سطر الخصم في الملخّص.
     - 🔴 توحيد النسختين: كانت نسخةٌ ثانية خاملة في
       Components/Pages/Pos/pos.css تلقّت تعديلات POS-Redesign-Fix
       (products-col) التي **لم تصل** للملف المُقدَّم — دُمجت هنا
       وحُذفت النسخة الخاملة (النمط الثامن: ميزةٌ يخفيها ملفٌّ خاطئ).
   ============================================================
   نظام تصميم شاشة نقطة البيع منقول من التمبليت المرجعي
   (pos_system_fixed.html): قشرة بملء الشاشة + لوحة طلب داكنة +
   لوحة منتجات بيضاء + فئات ملوّنة + ثيمات (official/luxury/fresh/fast).

   ملاحظات:
   - كل القواعد مقيّدة تحت .pos-shell حتى لا تتسرّب لبقية التطبيق
     (الملف محمّل عالمياً في App.razor).
   - بيئة الإمارات: الضريبة 5% والعملة AED تُعرَضان في الـ markup لا هنا.
   - radius=0 (حواف حادّة) كما في التمبليت.
