/* the genome: the image a core boots, embedded into the core when it is
compiled. an image is a file of little-endian 64-bit words placed at GORG,
as written by zc0 or by src/tools/build.zc and checked by mkgenome. the
build keeps every image in build/, never in the tree.
GENOME_FILE names the image. it defaults to "genome.bin" (or
"lsp_genome.bin" with USE_LSP_GENOME) and is found next to this header,
then in the directories given with --embed-dir, so that option selects
which image a core carries. the file needs a compiler with c23
#embed (clang 19 or gcc 15 and later).
no libc here: the microcore includes this on bare metal. */
