// The @filter above keeps discovery-driven builds from picking this sketch up
// off ESP32 at all. The guard below is the belt to that suspenders: an explicit
// `uno all` compiles every sketch regardless of filter, and an ESP32-only
// sketch has to compile away to nothing there rather than `#error` out, or the
// build reports what looks like a toolchain problem rather than an example that
// was never meant for AVR.
