 # - Manual movement only applies while a physical button or web switch is held/on.
 # - Position counter wraps back to zero after one full rotation.
 # - Onboard D1 Mini LED flashes briefly every time a motor step is issued.
+# - After WiFi connects, the onboard LED flashes the DHCP IPv4 address.
+# - IPv4 flash sequence is decimal digit based.
+# - A digit of 0 is represented as 10 flashes.
