-# Patch Ventoy's modsrc to allow a 64MB ESP. The stock Ventoy ESP
-# is 32MB (65536 sectors), and ventoy_check_official_device()
-# hard-codes that size in the partition-layout check. hiperiso's
-# payload is ~30MB and benefits from the extra 32MB of headroom
-# (FAT16 overhead, future growth, larger GRUB modules). Bump the
-# expected ESP size to 131072 sectors. This is the only Ventoy
-# source-level change we make.
