ESP32-S31 rainbow ring
RMT on GPIO0 drives a powered 24-pixel ring through the stock rainbow chase. The upstream program's byte order exchanges red and blue on GRB pixels; its source is unchanged. Serial announces the chase. Enable verbose in Serial to see the stock INFO lines. Unmodified pinned ESP-IDF development source on the bounded S31 simulator profile; no physical flashing.
