## Summary Extracted some changes from https://github.com/crosspoint-reader/crosspoint-reader/pull/500 to make reviewing easier This PR adds HAL (Hardware Abstraction Layer) for display and GPIO components, making it easier to write a stub or an emulated implementation of the hardware. SD card HAL will be added via another PR, because it's a bit more tricky. --- ### AI Usage While CrossPoint doesn't have restrictions on AI tools in contributing, please be transparent about their usage as it helps set the right context for reviewers.
