# System packages:
#   build-base, cmake, flex, bison, readline-dev -> build SFST from source
#   bash         -> Makefile.inc sets SHELL := /bin/bash
#   git          -> setuptools-scm derives the package version from git tags
#   python3, py3-pip, python3-dev -> python package + sfst musllinux wheel
#   uv           -> project dependency tooling (uv.lock)
#   nodejs, npm  -> build web frontend (docs:build via make docs)
#   rustup       -> Rust toolchain; Cargo.toml needs edition 2024 (Rust >= 1.85),
#                   newer than Alpine's packaged rust
