about
nx_meshlit_gate.nx -- GATE for CAP-PBR rung-1 (Lambert diffuse directional shading in nx_meshrender, over
nx_render_core). Proves the lighting law with HARD numbers: head-on face = full bright, perpendicular = 0,
45 deg = cos45 (the measured cosine law), back-face = clamped 0 (no negative light), a perpendicular face
ROTATED into the light relights to full (orbit relighting), and mr_shade actually brightens a lit face vs an
unlit one + respects an ambient floor; teeth: amb=0 + unlit = fully black (shading really darkens). expect_exit: 0
