$$ #176 floor triangles - retail light-setup trace (2026-07-06)
$$ Q: does retail set up the DYNAMIC magenta portal light (intensity=100,
$$    color 0.784,0,0.784) as a HARDWARE light applied to the corridor CELL?
$$    If yes -> retail's cell floor IS lit by the portal via D3D hardware T&L,
$$    so the per-vertex wedge pattern is retail-FAITHFUL, not an acdream bug.
$$
$$ config_hardware_light(d3dIndex@[esp+4], _D3DLIGHT9* out@[esp+8],
$$                       ulong cellID@[esp+0xc], LIGHTINFO* info@[esp+0x10])
$$   d3dIdx 1-10 = DYNAMIC (viewer / teleport PORTAL); 11+ = STATIC (wall torch, baked)
$$ Dumping the cellID lets us see WHICH cell the magenta portal is configured for.
