- Clone variant: mainline U-Boot v2025.10, boot.scr, clone DTS (type5) - Initramfs splash: archr-init.c with embedded BMP, sub-second display - Panel wizard: auto-detect with fsync persistence, evdev X-button reset - Hotkeys: adc-keys volume for clone, HP jack detection, brightness persist - Boot.ini: ASCII-only (no Unicode), GPIO check removed - ES wrapper: removed framebuffer blanking (preserves splash) - Build pipeline: both variants, splash generation, panel DTBOs - .gitignore: exclude large bootloader trees and build artifacts Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
