Two pio envs that build a tiny sketch reading /img.bin from LittleFS and calling epd_draw_image_with_border with the chosen color. Lets us verify the actual on-device pixel composition of the sync-fail (yellow) and no-WiFi (red) borders without standing up a server failure or pulling the WiFi cable. Each sim sets NVS err_border=1 before halting, so flashing back to the normal env afterwards exercises the 304 → clean repaint recovery path end-to-end.
