# game-build.sh — compile a Ludic GAME with the self-hosted compiler. The
# compiler resolves the game's own `import`s and auto-splices the Ludic runtime
# (runtime/native/core.ludic + its imports), exactly as the C compiler does.
# Headless only for now (renders to out.ppm). Run from the repo root.
#   ./selfhost/game-build.sh <selfhost-bin> <game.ludic> <out-binary>
