True floor-casting replaces the gradients and the projected seam lines:
every screen row lies at one depth, walked with a constant world-space
step and sampled from floor.png underfoot and ceiling.png overhead —
each maze cell wearing exactly one tile, so the artist's border IS the
cell seam. Distance shade and fog fold into the same per-pixel pass,
pixel buffers cache per texture (re-read when a painted file lands),
and the whole frame still clears 60fps with room to spare. Flagstones
and dark slabs ship as the starter files beside the other masonry.
