setScrollFactor(0) prevents camera scroll but NOT zoom displacement.
Added fixToScreen() utility that compensates object positions and scale
each frame based on current camera zoom. Applied to all scrollFactor(0)
UI elements in GameScene, Minimap, and BossArenaScene.

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).

- Remove existing tilemap/minimap textures before recreating (prevents
"Texture key already in use" error on second run)
- Expose __game and __debugKill for dev console testing

5 ecosystem tests verifying:
- Single species stabilizes with food
- Predator-prey dynamics reduce prey population
- Starvation without food leads to decline
- Mixed ecosystem runs 500 ticks without errors
- Lifecycle drives population renewal through egg hatching

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.

4 quick slots bound to keys 1-4. Active slot determines what F key
throws. Auto-assigns new items on collection. Clears slot when item
depleted. 15 new tests (213 total).

F key launches first inventory item toward mouse cursor as projectile.
Projectiles travel at 350px/s, expire after 2s, destroyed on hitting
non-walkable tiles. Color matches element's periodic table color.

Inventory uses real atomic/molecular masses (AMU). Same items auto-stack.
Respects weight limits and slot limits. Supports elements and compounds
via chemistry registries. 28 new tests (162 total).

Player spawns at walkable tile near map center. WASD controls movement
(150px/s, normalized diagonal). Tile collision with wall-sliding prevents
walking through acid pools, crystals, geysers. Camera follows player with
smooth lerp. 39 new tests (134 total).

Push must happen immediately after every commit — no accumulating
unpushed work. Updated both development order and task completion
checklists.
