"""
src/ — Backward-Compatibility Layer
====================================
⚠️  هذه الطبقة مُرحَّلة تدريجياً إلى modules/.
    سيتم حذف src/ بالكامل في v5.0.

خطة الترحيل (v4.2.0):
- src/database.py::HandwritingDB      → modules.core.handwriting_db
- src/reconstruction.py::reconstruct  → modules.nlp.reconstruction
- src/correction.py::append_feedback  → modules.nlp.feedback

الاستيرادات التالية تبقى صالحة للتوافق العكسي.
المكونات التي لم تُرحَّل بعد تستورد من src/ مباشرة.
