# cpu | gpu | hybrid (Phase 8) — see render/mod.rs's RenderBackend doc comment. `gpu` offloads
# tile shading and per-voxel face-visibility extraction to a wgpu compute shader; `hybrid` offloads
# only tile shading and keeps meshing on CPU. Unrecognized values, and `gpu`/`hybrid` on a machine
# with no compatible GPU adapter, fall back to `cpu` with a logged warning rather than crashing.

# Thread count for the rayon pool that renders a batch of dirty chunks in parallel (see
# config.rs/main.rs — a single 16x16 tile is too small for rayon to help within itself, so the
# parallelism target is many chunks in flight at once). `auto` (default) uses
# std::thread::available_parallelism(); set a positive integer to override (0/garbage also falls
# back to auto).

# server | consumer — tunes how many dirty-chunk entries are pulled off the Redis stream per
# xread cycle before being rendered in parallel. `server` (default) batches more aggressively —
# many small batches so every core on a many-core Xeon-style box stays fed; `consumer` uses
# fewer, larger batches, less scheduling overhead per chunk on fewer/faster cores. Unrecognized
# values fall back to `server`, matching this project's own primary deployment target.
