+# Build a pixpat wheel for the given target architecture.
+#
+# Usage: pixpat-python/scripts/build_wheel.sh <x86_64|aarch64>
+#
+# Meson is invoked from setup.py during the wheel build; this script just
+# selects the target arch and hands off to `python -m build`. The meson
+# build dir lands at pixpat-python/build-<arch>/native/, so cross-compiling
+# both arches in turn keeps each arch's compile incremental.
+#
+# Prerequisites:
+#   - meson, ninja in PATH (e.g. `pip install meson ninja`)
+#   - For aarch64: gcc-aarch64-linux-gnu, g++-aarch64-linux-gnu
+#     (sudo apt install gcc-aarch64-linux-gnu g++-aarch64-linux-gnu)
+#   - Python with `build` package: pip install build
