# ------------------- Stage 1: Build Stage ------------------------------
# We use Alpine for smaller image size (~329MB vs ~431MB for Debian slim).
# Trade-off: We must install build tools to compile native extensions (cryptography, etc.)
# since pre-built musl wheels aren't available. Debian -slim would skip compilation
# but produces a larger final image due to glibc wheel sizes.
