+# 📦 Optimized Multiplatform Docker Build Workflow
+# ===============================================================
+#
+# This workflow builds multiplatform Docker images more efficiently by:
+# 1. Building AMD64 and ARM64 images in parallel on native runners
+# 2. Using matrix strategy to run builds simultaneously
+# 3. Combining results into a single multiplatform manifest
+#
+# This approach is much faster than cross-compilation with emulation.
