debug: test with gr.Interface instead of gr.Blocks

debug: minimal echo app to isolate Space vs code issue

fix: explicit server_name=0.0.0.0 server_port=7860 share=False (Spaces-safe)

fix: self-launch with ssr_mode=False, GRADIO_SSR_MODE=False already set on Space

debug: print SPACE/HF/GRADIO env vars to understand detection

fix: detect Space via SPACES_ZERO_GPU/SPACE_ID, skip self-launch on Space

debug: wrap init/build/launch in try/except to capture exact error

fix: demo.launch(ssr_mode=False) only, match working Space pattern

fix: SPACE_ID guard for __main__, let pySpaces launch on Space

fix: guard __main__ with 'spaces' not in sys.modules, let pySpaces launch

fix: remove __main__ block, let pySpaces handle launch entirely

fix: remove server_name/port (let pySpaces handle), disable SSR

fix: disable SSR (Node.js proxy may be crashing on Space)

fix: match official Gradio template pattern (module-level demo + __main__ launch)

debug: wrap build() in try/except to capture Space crash

fix: guard __main__ for Space (pySpaces handles launch)

cleanup: remove spike/ directory
