Phase 3: World generation — procedural tilemap for Catalytic Wastes

Browse Source 
- simplex-noise with seeded PRNG (mulberry32) for deterministic generation
- Biome data: 8 tile types (scorched earth, cracked ground, ash sand,
  acid pools, acid shallow, crystals, geysers, mineral veins)
- Elevation noise → base terrain; detail noise → geyser/mineral overlays
- Canvas-based tileset with per-pixel brightness variation
- Phaser tilemap with collision on non-walkable tiles
- Camera: WASD movement, mouse wheel zoom (0.5x–3x), world bounds
- Minimap: 160x160 canvas overview with viewport indicator
- 21 world generation tests passing (95 total)

- [x] 3.5 Resource placement — geysers on acid-shallow zones, mineral veins on ground (`src/world/generator.ts`)
- [x] 3.6 Camera — WASD movement, mouse wheel zoom (0.5x–3x), bounds clamping (`src/world/camera.ts`)
- [x] 3.7 Minimap — canvas-based 160x160 overview, viewport indicator, border (`src/world/minimap.ts`)

## Up Next: Phase 3 — World Generation
## Up Next: Phase 4 — Player Systems
- [ ] 3.1 Tilemap system (Phaser Tilemap from data-driven tile definitions)
- [ ] 3.2 Biome data (`biomes.json` — Catalytic Wastes)
- [ ] 3.3 Noise generation (simplex-noise, seed-based)
- [ ] 3.4 Tile types (scorched earth, acid pools, crystal formations, geysers, mineral veins)
- [ ] 3.5 Resource placement (ores/minerals based on biome params + noise)
- [ ] 3.6 Camera (follow player, zoom, clamp to map bounds)
- [ ] 3.7 Minimap
- [ ] 4.1 Player entity + WASD controller
- [ ] 4.2 Inventory (weight-based, element stacking)
- [ ] 4.3 Element collection from world objects
- [ ] 4.4 Crafting (chemistry engine integration)
- [ ] 4.5 Projectile system (throw elements/compounds)
- [ ] 4.6 Quick slots (1-2-3-4 hotkeys)
