+ * {{PROJECT_NAME}}.ino -- Pushbutton input with edge detection
+ *
+ * Detects button presses (rising edge only) and prints to Serial:
+ *
+ *     Button pressed! (count: 1)
+ *     Button pressed! (count: 2)
+ *
+ * All logic lives in lib/app/{{PROJECT_NAME}}_app.h which depends
+ * on the HAL and Button interfaces, making it fully testable
+ * on the host without hardware.
+ *
+ * Wiring (active-low, no external resistor needed):
+ *   Pin 2    -> one leg of the button
+ *   GND      -> other leg of the button
+ *   (uses INPUT_PULLUP internally)
+ *
+ * Serial: 115200 baud
