# Layout:
#   data/                asset tree the engine loads: INDEX catalog plus
#                        music/, sprites/, ... (see docs/asset-pipeline.md)
#   raptor/build/bin/    built engine
#
# The engine resolves the catalog and assets relative to its working
# directory, so we run it from data/. Saves and SETUP.INI go to
# ~/.local/share/Raptor (SDL pref path) — nothing is written into the repo.
