# Build distributable desktop executables with the Godot export pipeline.
#
# Requirements:
#   - Godot 4.3 (or the version in project.godot `config/features`) on PATH,
#     with export templates installed (see docs/RELEASING.md).
#   - Run from the repository root.
#
# Produces:
#   build/step-line-linux-<version>.x86_64
#   build/step-line-windows-<version>.exe
#   build/step-line-macos-<version>.zip
#   build/step-line-web-<version>.zip  (Godot web build: static hosting, no threads)
