# NOTE: include/ is intentionally not copied — it's an empty directory (git
# can't track empty dirs, so it's absent in a fresh checkout) and no header
# lives there; all headers are under src/. The Makefile's -Iinclude search
# path harmlessly tolerates its absence.

# The Makefile does `include tests/*.mk` at the top level, so those files
# must be present for make to parse — we only build the main binary target
# though, not the tests themselves.
