	# Cowork's bundled VM launcher only probes the Debian OVMF locations
	# (/usr/share/OVMF/OVMF_CODE{_4M,}.fd) and derives the matching
	# variable-store template by replacing OVMF_CODE with OVMF_VARS in
	# that path. Gentoo ships the raw firmware via sys-firmware/edk2-bin
	# (pulled in by qemu) under /usr/share/edk2/OvmfX64/, so rewrite the
	# probe list inside app.asar to point there. The replacement is padded
	# to the original length so the asar header's file offsets stay valid
	# (in-array whitespace is valid JS; Electron's asar integrity fuse is
	# not enforced on Linux, so the stale header hash is harmless).
