Replaces the single flat grey tile. Adds tools/build_tiles.py (atlas builder with edge-blending + tone matching), paint_terrain.py (surgical tile-plane repaint: asphalt base, concrete pads, dirt blobs, groove patches near wax, rubble clumps), jitter_wax.py, render_map.py (offline map preview), and check_assets.py. Also fixes the arena harness being rigged: both wax fields sat ~12 cells from BotA and ~18 from BotB, so BotB starved for map reasons, not balance reasons. Arena wax is now mirrored (7.1/18/18/19.8 from both starts). Seep interval 90 -> 20 after telemetry showed the slower rate still drained both economies.
