compose.py crashes verbatim on a stock Mac with 'OSError: cannot open resource' - it hard-codes /Library/Fonts/SF-Pro-Display-Black.otf, a font Apple doesn't ship and the docs never mention; swapping in an installed font, it does composite a clean 1290x2796 scaffold (correct verb/descriptor hierarchy + device frame). The actual high-converting output still needs the paid Nano Banana Pro / Gemini MCP, which couldn't be exercised here.
