- ST7305 driver with persistent 15KB DMA buffer (fix use-after-free +
WDT lockup that caused freeze after flash)
- Reset timing fix: 150ms after reset, 50ms after init
- DTS: i2s0 mclk 16, bclk 9, ws 45, out 8, in 10 - fixes GPIO5 conflict
- i2c0 uses esp32-i2c-master, SDMMC 1-bit
- device.properties: colorDepth 16, fontSize 20, DefaultDark
- Amp GPIO46 init in initBoot
- Buttons: two-button control GPIO18 (cycle) + GPIO0 (select)
