 # ============================================
 # Fast Production Dockerfile
-# Uses pre-built base image - build time ~2-3 min vs 15-20 min
+# Single-stage build using CI pre-built assets
+# Saves time by skipping multi-stage node/composer builders
+# ============================================
+#
+# This Dockerfile expects:
+#   - vendor/ already populated (from CI composer-install step)
+#   - public/build/ already populated (from CI build-frontend step)
+#
+# Build time: ~5-7 min (vs 15-20 min with multi-stage Dockerfile)
 # ============================================
