feat: multi-layer world — temperature, gas, pressure, light as parallel per-chunk arrays
- Removed temp from Cell (13→9 bytes), added temps/pressure/gas_type/gas_density/light arrays to Chunk
- Layer access via grid.get_temp()/set_temp()/get_gas()/set_gas()/get_pressure()/set_pressure()/get_light()/set_light()
- cells_swap swaps all layers, set_material sets default_temp
- heat_transfer refactored to direct array access on temps[] (no Cell copy)
- CA rules refactored: cell.temp → grid.get_temp()/set_temp()
- gas_step: gas flow (rise, spread), fire produces CO2+smoke, steam condenses to water, acid+organic→poison gas
- pressure_step: pressure equalization for connected non-solid cells
- light_step: world-space persistent lighting, updated every 10 ticks, ray-cast line-of-sight
- Gas damage: poison gas damages entities, CO2 suffocates, applied before ca.step()
- Multi-section chunk serialization (VWM1 magic + cells + temps + gas + pressure + light)
- Old 12-byte chunk format auto-detected for backward compat
- AI spectrum: new gas + pressure spectrums, light spectrum uses world-space fallback
- Protocol: gas/pressure spectrum commands
- pre_dirty mechanism: layer steps process pre-clear dirty rects for cross-cell diffusion
- 14 new multilayer tests, all 185 tests + 14 scenarios pass
- Benchmark: 85.9 FPS (graphics surface, was 128 pre-layers — 33% regression from 4 new layer steps)

feat: GPU optimization — lighting, viewport CA, benchmark mode, 531 FPS
- Resolution: 8x8 world cells, 2x2 UI cells (UI_SCALE=4)
- GPU lighting: vertex-shader computed, light source list buffer (max 64)
instead of O(N×R²) grid scan, O(N×S) per cell
- Viewport-aware CA: iterate only active chunks, not all 250×250
- Flat array entity/item/shadow maps instead of HashMaps
- Flat 128-entry ASCII atlas array instead of HashMap lookup
- Partial grid upload: viewport + 30-cell margin only
- Pre-allocated viewport arrays in renderer structs (zero alloc/frame)
- Skip CPU lighting for GPU modes (pass None)
- Benchmark mode: --mode benchmark with per-subsystem timing
- GpuLightSource struct, light_count in push constants
- gather_sources_in_range() for viewport-scoped source gathering
Benchmark (600 ticks, release):
Graphics: 531 FPS (was 386, +38%), render 1013us (was 1699us, -40%)
ASCII: 402 FPS (was 313, +28%), render 1502us (was 2346us, -36%)
All 171 tests + 14 scenarios pass.
