-- out.lua —— VML 跨语言「输出」判据（期望恰好三行，见 run-langs.sh）
-- out.lua -- VML cross-language "output" probe (exactly three lines, see run-langs.sh)
-- 写法照 corpus/lua/skel.* —— 共享库同时提供 println_str / println_int。
-- Pattern follows corpus/lua/skel.* -- the shared library provides both println_str / println_int.
