m52xq build script

build.sh

#!/bin/bash

## Build script for Samsung Galaxy M52 5G (m52xq) - LineageOS 23.2
## Usage:
##   ./build_m52xq.sh          # Full clone + build
##   ./build_m52xq.sh sync     # Clone/sync repos only, no build
##   ./build_m52xq.sh build    # Build only (assumes repos already cloned)

# REMOVED: set -e (We want the script to power through errors)

# Force UTF-8 so box-drawing/status characters render correctly in any
# terminal/container regardless of its default locale.
