+# Output Compression Control Module
+
+This Go package (`obidefault`) provides a simple, global configuration mechanism for toggling output compression behavior across an application.
+
+## Core Features
+
+- **Global Compression Flag**: A package-level boolean variable `__compress__` (default: `false`) controls whether output should be compressed.
+- **Read Access**:  
+  - `CompressOutput()` returns the current compression setting as a boolean.
+- **Write Access**:  
+  - `SetCompressOutput(b bool)` updates the compression flag to a new value.
+- **Pointer Access**:  
+  - `CompressOutputPtr()` returns a pointer to the internal flag, enabling indirect modification (e.g., for UI bindings or reflection-based updates).
+
+## Design Intent
+
+- Minimal, side-effect-free API.
+- Thread-safety *not* guaranteed — intended for use in single-threaded initialization or controlled environments.
+- Encapsulation via unexported variable `__compress__`, enforced through accessor functions.
+
+## Typical Usage
+
+```go
+// Enable compression globally:
+obidefault.SetCompressOutput(true)
+
+if obidefault.CompressOutput() {
+    // Apply compression logic (e.g., gzip, brotli)
+}
+```
+
+## Notes
+
+- The double underscore prefix (`__compress__`) signals internal/private status (convention, not enforced).
+- Designed for runtime configurability without recompilation.
