render_textured.py samples the game textures with the quads' texu/texv/texz planes, z-buffered. Empirical finding: the planes are texscale-encoded (2^16) homogeneous coords needing the exact perspective_divides mapping (texu/texz * .Cturn_z_to_tex from FOOTER.SS) -- measured texu/texz ~0.12 on the ground quad. That final texel-coordinate calibration is a precise reverse-engineering step against EOF.C, not a guess; left as the last mile. The verified M3 result is the texture DECODE: the netdeath textures are real game art (texstore.py). Geometry + texel format are both solved from the live wire.

"""Proof of texture sampling on real battle geometry: each textured quad's

texu/texv planes sample a real game texture (nearest, tiled) with z-buffer.

Binding note: per-quad texid->handle binding is not yet resolved, so this maps

all textured surfaces to one representative texture to demonstrate the
