+# Cross-platform build script for BEX Engine
+# Targets GLIBC 2.31+ (Ubuntu 20.04 / Debian 11 / most modern distros)
+#
+# Strategy: Use musl-static or manylinux2_28 build environment
+# This ensures the resulting binary works on:
+#   - Ubuntu 20.04+
+#   - Debian 11+
+#   - Fedora 34+
+#   - Alpine (musl)
+#   - RHEL 8+
+#   - Any system with GLIBC >= 2.28
+#
+# Usage:
+#   ./build-portable.sh          # Build dynamically linked (GLIBC 2.28+)
+#   ./build-portable.sh --musl   # Build fully static (no GLIBC dependency)
+#   ./build-portable.sh --docker # Build in Docker for reproducibility
