1// nx_multilang_render_gate.nx -- proves native rendering of all four broadened languages, NO fake green:
2// Russian (привет друг), Belarusian (вітаю любоў -> exercises І and Ў), Ukrainian (привіт дякую -> exercises І),
3// Polish (cześć miłość -> exercises ś ć ł, native lowercase diacritics). Each onto its own video frame; asserts
4// each sets glyph pixels. Eyeball -> knowledge/nx_multilang_render.png (4 stacked panels). expect_exit: 0 license_tier: ORIGINAL
