+// 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.
