# Pure C, no C++/STL dependency (ANDROID_STL=none set in build.gradle) —
# links only against jnigraphics (for AndroidBitmap_* functions).

# This library is only ever loaded on Android API 21-30 (see
# BlurThreadPool.kt / LegacyBlurController.kt) — API 31+ uses the GPU
# RenderEffect path and never touches this at all.
