Previous versions required manual SPI library modification to prevent SD card read failures:

Both PlatformIO and Arduino IDE users needed to modify the MISO default pin to 26 in the SPI library. For example, in Arduino IDE's package path esp32\hardware\esp32\1.0.4\libraries\SPI\src\SPI.cpp:

if(sck == -1 && miso == -1 && mosi == -1 && ss == -1) {
    _sck = (_spi_num == VSPI) ? SCK : 14;
    _miso = (_spi_num == VSPI) ? MISO : 12; // Change to 26
    _mosi = (_spi_num == VSPI) ? MOSI : 13;
    _ss = (_spi_num == VSPI) ? SS : 15;

This was necessary because the hardware uses two hardware SPI connections for screen and SD card. HSPI's default MISO pin 12 is used for flash voltage setting during ESP32 boot, and pulling it up before power-on prevents chip startup. We replaced it with pin 26.
