Starfish: Lightweight GPU-first research operating system

Starfish is the inspectable operating-system layer beneath Yeho applications, YUI interfaces, and permissioned Yodi control. This diagram follows current research from UEFI firmware through the compact kernel, FIT64 filesystem, userland, and first pixels while keeping the connected software route visible.
