The build_grub2_204.sh script was patching Ventoy's modsrc from 65536 to 131072 sectors (bumping expected ESP size from 32MB to 64MB). After reducing our ESP size to 32MB to match Ventoy exactly, this patch now needs to be reversed (131072 -> 65536) so the GRUB2 layout check accepts our 32MB ESP. Built GRUB2 EFI binary with corrected checks. Reinstalled payload.
