// 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.
