    # LTspice engine is GATED. The backend image ships Wine 11.10 + the prefix,
    # the host carries ./ltspice (exe/lib/examples), but LTspice v26's threads
    # spin in userspace during startup under headless Wine in this slim image
    # (runs fine on the dev desktop). Without LTSPICE_DIR the engine reports
    # "unavailable" and fails fast instead of hanging.
    #
    # Ruled out (don't re-tread): Wine version (11.10 matches dev), the ini
    # first-run seed, the X display (Xvfb up), GL/EGL/vulkan libs, fonts,
    # 32-bit subsystem, color depth, and the entire CUPS/print path (cupsd up,
    # CUPS_SERVER, libcups removed -- all still spin). Next: a userspace
    # backtrace of the spinning thread, or pivot to running mcltspice on a
    # real desktop and calling it remotely. To resume, uncomment both blocks:
    # volumes:
    #   - ./ltspice:/opt/ltspice-src:ro

    #   - LTSPICE_DIR=/opt/ltspice
