# .include "macro.inc" (found via -I"$REPO/include") pulls the GTE assembler macros (mvmva/…) so drafts
# with GTE inline asm assemble -- the real build gets these via include_asm.h, which the permuter's base.c
# omits (and -DPERMUTER disables). Pure macro defs -> byte-neutral for non-GTE functions. (Phase 24 T3)
