Extracts buildQrUrl and generateZoneQrs with injectable I/O deps and adds tests/scripts/generate-qr.test.ts (20 tests). Refactor + tests originated from a concurrent working session; this commit adds on top: - import.meta entry guard — the unconditional top-level main() executed on test import and wrote (sometimes truncated) PNGs into public/qr - typed vi.fn generics in makeDeps so strict tsc passes Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01CPf5Rc8QPx6V8KLEEgfKEQ
