#!/usr/bin/env bash
# Build release wheels for hyper_fingerprints.
#
# Usage:
#   ./build.sh              # build wheel + sdist
#   ./build.sh --release    # same (default)
#   ./build.sh --debug      # debug build (faster compile, slower runtime)
#
# Output:
#   target/wheels/*.whl     # pre-compiled wheel (abi3, linux x86_64)
#   target/wheels/*.tar.gz  # source distribution
#
# Requirements:
#   - Rust toolchain (rustup.rs), >= 1.83
#   - maturin: pip install maturin
#   - Python 3.9+
