# Rune Goblin RPG sandbox — Hugging Face Docker Space.
#
# Runs app/rpg_app.py (the Gradio canvas RPG) under uvicorn. No model weights
# ship: the drawn-rune vision model is OFF (RG_USE_MODEL=0 -> deterministic rule
# engine reads glyphs) and NPC dialogue is a remote HTTP call to the Modal API
# (RG_DIALOGUE_API_* set as Space secrets). Small, CPU-only image.
