// The variable is already defined in avr_millis_timer_null_counter.hpp when needed,

// so redefining it here caused multiple-definition linkage errors.

// Provide a single consolidated weak timer_millis symbol for AVR tiny/x-y parts

// whose cores do not export it, satisfying MS_COUNTER binding in led_sysdefs_avr.h.

// This complements avr_millis_timer_null_counter.hpp when that TU is not built.
