Validate and Test / validate-patches (push) Failing after 12s
Background thread stack (500 bytes) overflows after ~50 draw_frame calls. __loopHook (called after loop() returns) is the fallback. With delay(1000), it ran once per second — too slow. Reducing to delay(10) keeps RPC processing responsive.
