/*
 * blink.ino -- LED blink with button-controlled speed
 *
 * This .ino file is just the entry point. All logic lives in
 * BlinkApp (lib/app/blink_app.h) which depends on the HAL
 * interface (lib/hal/hal.h), making it testable on the host.
 *
 * The build script auto-discovers lib/ subdirectories and passes
 * them as --library flags to arduino-cli, so angle-bracket includes
 * work for project-local libraries.
 *
 * Wiring:
 *   Pin 13 (LED_BUILTIN) -- onboard LED (no wiring needed)
 *   Pin 2                -- momentary button to GND (uses INPUT_PULLUP)
 *
 * Serial: 115200 baud
 *   Prints "FAST" or "SLOW" on button press.
