apc-io/apc-firefox-os ? reverse-engineered prompt

Build me the APC Firefox OS project so it boots and runs well on APC hardware, with the same focus this repo describes.

I want the device to support the basic APC peripherals people would expect, like hardware keys, Ethernet, USB storage, USB camera, and a generic Bluetooth dongle. It should also handle hotplug as smoothly as possible, and the main interface should be usable on the device without obvious layout bugs or broken tutorial flow. If there are known limitations, leave clear notes in the docs, especially around WiFi, video playback, camera preview behavior, and any hardware that still needs to be connected before boot.

Please make the build and setup instructions easy to follow, and keep the README and guide clear enough that someone can get from a clean machine to a working image without guessing. If you need to check current Mozilla docs or old APC references online, do that too.
