Goal: move from using prebuilt images to owning the whole build — Yocto layers and recipes, U-Boot scripting and environment, kernel configuration and out-of-tree modules, udev rules, embedded networking, flash-aware storage, on-target debugging, read-only root filesystems, and production systemd — ending with a fully custom Yocto image booted in QEMU.
