+# ── DebugView logging toggle ────────────────────────────────────
+# When ON, every ANS_DBG(...) call across the whole tree expands to an
+# OutputDebugStringA() call visible in Sysinternals DebugView (Dbgview.exe).
+# This is the single switch for verbose runtime diagnostics in ANSLPR,
+# ANSCV (RTSP lifecycle, HW decoder auto-config), ANSODEngine (NV12 fast
+# path, ORT/TRT engine selection), ANSFR (face recognizer state), etc.
+#
+# Enable it to diagnose field issues (e.g. "ALPR worked for a while then
+# stopped"), then turn it back OFF for production because every ANS_DBG
+# call adds a kernel round-trip and string formatting cost.
+#
+# Usage:
+#   cmake -B build -DANSCORE_DEBUGVIEW=ON    # enable
+#   cmake -B build -DANSCORE_DEBUGVIEW=OFF   # disable (default)
+#
+# Or toggle in CLion/VS: edit the cache variable ANSCORE_DEBUGVIEW.
