# =============================================================================
# Dockhand Docker Image - Baseline Build (Alpine/musl, amd64 only)
# =============================================================================
# For older x86_64 hardware without AVX2/SSE4.2 (TrueNAS, older Intel Atom/Celeron)
# Uses node:24-alpine (musl libc) compiled conservatively for all x86_64 CPUs.
# The Wolfi/glibc build crashes with SIGILL on CPUs that don't support the
# microarchitecture level Wolfi packages are compiled for.
# =============================================================================

# Stage 1: Application Builder (Alpine - musl-compatible native addons)
# -----------------------------------------------------------------------------
# IMPORTANT: Must use alpine builder so native addons (better-sqlite3) are
# compiled against musl libc, not glibc. Cross-ABI copies would not work.
