Usage: ./run-open-question-tests.sh [--source PATH] [--assets-root PATH] [--include-layer-fallback]

Runs ONLY the Task 1 open-question static/fixture selectors.
Binary fixtures are selected by an exact whitelist in:
  open_questions/config/fixture_manifest.json

Default logical fixtures:
  private-assets/Maps/Town Defence/Town Defence.dat + Town Defence.map
  private-assets/data/sprites/Tileset.rxx

Optional fallback, used ONLY when the primary map does not cover layered/generated terrain:
  --include-layer-fallback
  -> private-assets/Maps/The Barbarian King/TBK01/TBK01.dat + TBK01.map

No recursive fixture discovery is performed.
This script does NOT run build-android.sh and does NOT execute Task 1 implementation.
