/* HawkHealth — Week 1 RTOS concept sketch (Wokwi, ST Nucleo-C031C6).
 *
 * Two independent FreeRTOS tasks on a real ST Nucleo. The point of this sketch is
 * to SEE concurrency: two for(;;) loops that each act like they own the CPU, taking
 * turns because each one BLOCKS (vTaskDelay) instead of spinning.
 *
 * Notice the shape: xTaskCreate + vTaskDelay are the EXACT FreeRTOS calls HawkHealth
 * uses on the STM32F767. Only the I/O lines (digitalWrite / Serial) differ from
 * HawkHealth's hh_led_toggle() / hh_putc(). That difference is the "platform seam."
 *
 * FIRST-RUN NOTE: this is a starter.  Wokwi uses the Arduino framework for STM32.
