C++ code in this project must never depend on Blueprint assets. Dependencies flow one way only: Blueprints may depend on C++, never the reverse.

**Why:** The user has stated this as a firm architectural principle. C++ that references BP assets (by soft class path, string, or otherwise) inverts the normal layering and creates fragile coupling to content.

**How to apply:** When suggesting UMG patterns, do not propose solutions that involve C++ doing `CreateWidget` on a WBP class, loading a WBP via `FSoftClassPath`, or otherwise reaching from C++ into `/Game/...` content. For UMG work initiated from C++, construct widget trees programmatically in C++ (override `RebuildWidget`, manipulate `WidgetTree` directly). Blueprint subclasses of C++ widget classes are fine — that's BP depending on C++.
