- panic screen now draws embedded ohMyLogo.png (384px RGBA, gen_panic_logo.py); background color sampled from image corners so screen bg matches logo bg - F2: include/utsm/fbcon.h unified framebuffer console (pixel/blend/fill/rgba-image/text with FBCON_HAVE_FONT opt-in); panic.c migrated onto it - build.ps1 regenerates panic_logo_data.inc when ohMyLogo.png changes
