Expand beyond vertical slice with two new biomes and massive chemistry expansion: Chemistry: +20 real elements (Li→U), +39 compounds (acids/salts/oxides/organics), +85 reactions (Haber process, thermite variants, smelting, fermentation, etc.) Biomes: Kinetic Mountains (physics/mechanics themed) and Verdant Forests (biology/ecology themed), each with 8 tile types and unique generation rules. Creatures: 6 new species — Pendulums/Mechanoids/Resonators (mountains), Symbiotes/Mimics/Spore-bearers (forests). Species filtered by biome. Infrastructure: CradleScene biome selector UI, generic world generator (tile lookup by property instead of hardcoded names), actinide element category. 487 tests passing (32 new).
