Two crashes found flashing to real hardware: - epd_display_stream's 4KB SPI chunk buffer was a stack local, but the default main task stack (3584 bytes) is smaller than that alone -- Guru Meditation stack protection fault. Made it static instead, and bumped CONFIG_ESP_MAIN_TASK_STACK_SIZE to 8192 for headroom in the rest of the boot call chain (provisioning -> QR render -> eventually the HTTP fetch cycle all run in this one task). - epd_wait_busy() polled with a 1ms vTaskDelay, which rounds down to 0 FreeRTOS ticks at the default 100Hz tick rate -- so it never actually blocked, tight-spinning the CPU for the panel's real refresh time (15-30+s for a full-color pass) and starving the idle task long enough to trip the 5s task watchdog. Bumped to 20ms, safely >=1 tick regardless of tick rate. Also updates the EPD pin defaults to the board's actual wiring (CLK=20 MOSI=19 CS=18 DC=9 RST=10 BUSY=11), confirmed working on hardware.
