#!/usr/bin/env bash
#
# Build a statically-compiled, self-contained epp-cli binary.
#
# Prerequisites: curl, tar (macOS also needs Xcode CLT / brew).
# The script downloads static-php-cli (spc), compiles a micro PHP runtime
# with the required extensions, builds the PHAR, then combines them into
# a single executable.
#
# Usage:
#   ./build-static.sh              # build for current platform
#   SPC_PHP_VERSION=8.3 ./build-static.sh   # override PHP version
#
