- Created hal/esp32s3.rs with MCU primitives (SPI, I2C, USB, UART, timer, MAC) - Created hal/nrf52840.rs with shared nRF boilerplate (interrupts, bus wrapping, VBUS, MAC) - Moved SH1106 OLED driver from display/ to driver/ (clear separation from app code) - Board esp32s3.rs now delegates MCU init to hal, keeps only peripheral wiring (RadioParts) - nRF board files use hal for shared StaticCell patterns, mac_address, interrupt bindings - Board files still own pin assignments and peripheral construction
