M5 integrate: recognizable arena interior -- verified divide makes texturing land

render_final.py applies the oracle-verified perspective divide (texel8 = texu/texz*2048, the *8 from the '3 integer bits') with per-quad texel tiling. The battle frame now reads as a real first-person arena interior: a tiled floor receding correctly to the vanishing point (panels shrinking toward the horizon), a paneled ceiling, and a horizon band of structures. The verified divide fixed the tiling frequency that washed out earlier attempts. Monochrome because surfaces map to one texture family -- the exact texid->handle binding needs the board texture-RAM model (texels go to board tex memory via TXDN/io, not watchable DRAM; confirmed by the storage trace). Geometry, perspective, texel decode, and the divide are all solved from the live wire; per-surface texture selection is the last remaining piece.
