Based on 62fixolab/Latest-Bazzite-AMD-BC-250-Patched-Images @ 347fd4d. Adds on top of the fork: - recipes/bc250-console-gnome.yml: governor + gnome-remote-desktop + openssh-server, sshd enabled, hhd.service masked, no signing module (local build + ISO path) - files/console/usr/bin/bc250-remote-setup: one-time on-box SSH/RDP setup - files/console/usr/lib/bootc/kargs.d/50-bc250-ttm.toml: ttm memory kargs - BUILD-CONSOLE.md: build -> ISO -> validation instructions files/console/ is separate from files/system/ so the 40-CU unlock tooling stays out of this stable 24-CU image.
