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).

UIScene renders as overlay on top of GameScene:
- Health bar (top-left) with color transitions green→yellow→red
- 4 quick slots (bottom-center) with active highlight, item symbols and counts
- Inventory weight/slots info (bottom-right)
- Controls hint (top-right)
GameScene pushes state to Phaser registry each frame.
Phase 4 (Player Systems) complete — 222 tests passing.
