+# --- CRITICAL INSTALLATION STEP ---
+# We install the AI engine separately with three safety flags:
+# 1. --extra-index-url: Points to the pre-built CPU library.
+# 2. --only-binary :all: STRICTLY forbids compilation. If the pre-built file isn't found, it will error immediately (fail fast) rather than trying to compile for 30 mins.
+# 3. --no-cache-dir: Keeps the image small.
+RUN pip install --no-cache-dir --only-binary :all: \
