+/**
+ * Unreal Engine reflection-macro preprocessor for C++ source.
+ *
+ * Tree-sitter does not expand C preprocessor macros, so Unreal's reflection
+ * markers (`UCLASS(...)`, `UFUNCTION(...)`, `MODULENAME_API`, ...) are parsed
+ * verbatim. The result is mis-parsed declarations: in `class BRAWLUI_API
+ * UMyClass : public UObject`, tree-sitter-cpp captures `BRAWLUI_API` as the
+ * class name and the rest of the declaration becomes structurally wrong.
+ *
+ * This module elides those macros from the source text BEFORE tree-sitter
+ * parses it. Replacement is **length-preserving** (each elided byte becomes
+ * a space, newlines preserved) so byte offsets and line/column positions
+ * tree-sitter reports remain identical to the original file. Symbol
+ * locations in the graph stay accurate.
+ *
+ * A cheap detection guard short-circuits files that don't look like UE
+ * sources, so non-UE C++ codebases pay no cost.
+ *
+ * Pure function — no tree-sitter dependency, safe for worker threads.
