// ---------------------------------------------------------------------------
// Runtime fault hook
// ---------------------------------------------------------------------------
// Weak default for strucpp::iec_runtime_fault (declared in iec_fault.hpp).
// On MCU firmware (compiled -fno-exceptions) the runtime calls this instead
// of throwing on an unrecoverable fault (null deref, array OOB, bad located
// address). Default behaviour: halt. A VPP HAL may provide a STRONG override
// to signal the fault its own way — blink a status LED, sound an alarm,
// reboot, etc. Kept free of <Arduino.h> so this TU stays macro-clean.
