  "comment": "The opponents the page offers, weakest first: the ceramics ladder, from raw ground to precious glaze. Each dir holds a model.onnx + model_meta.json (the meta carries the Elo and parameter count the menu shows; run/checkpoint stay internal). Five of the swatch colours are the game's own tile glazes; Sand and Clay are the two raw earths beneath them. scripts/deploy_player.sh ships this whole tree.",

    "comment": "The next rungs of the ladder, in order, for agents stronger than Cobalt. When a newly trained net beats the current best, export it (scripts: onnx_export --ckpt ... --elo ... --out web/player/model/<id>), name it the NEXT name on this list, add it below with a fitting swatch, and make it the default. Do not rename existing bots.",
