# BEX Engine — Portable Build Container
# Produces binaries compatible with GLIBC 2.31+ (Ubuntu 20.04+, Debian 11+)
#
# Usage:
#   docker build -t bex-builder .
#   docker run --rm -v $(pwd)/dist:/out bex-builder
#
# Or build fully static (musl):
#   docker build --target musl -t bex-builder-musl .
#   docker run --rm -v $(pwd)/dist:/out bex-builder-musl
