BOXHEAD v0.2.0 — HD COMPLETE UPGRADE

FUNCTIONAL BASELINE
- Built directly on v0.1.8, which runtime-tested working zombie spawning/chasing, projectile travel, 5-damage pistol hits, atomic ammo consumption and queue-safe firing.
- The v0.1.8 fire reactions, projectile movement/substep logic, wave spawning budget logic and custom entity gameplay definitions remain functionally unchanged.

HD MODEL PASS
- Rebuilt Zombie, Mutant, Giant and Mangled native D.A.I. meshes with substantially higher geometric detail while preserving their gameplay hitbox definitions.
- Rebuilt light bullet, heavy bullet and pellet carrier meshes with rounded multi-sided projectile silhouettes and dedicated materials.
- Rebuilt Pistol, Pump Shotgun and Hand Cannon item models from simple three-block prototypes into detailed multi-part 3D models.
- Preserved the known-good first-person 90-degree orientation and existing third-person transforms.
- Fire-state models now visibly move slides/pumps/upper assemblies while retaining the same custom_model_data switching system.
- Rebuilt light rounds, heavy rounds, shotgun shells and spent casings as detailed 3D inventory models.

HD TEXTURE PASS
- Replaced 8x8 infected materials with 64x64 hand-authored procedural pixel textures: skin, clothing, blood, eyes and archetype-specific flesh.
- Added dedicated 64x64 firearm materials for blued steel, parkerized metal, bright edges, rubber grip, walnut stock, brass, shell plastic and muzzle surfaces.
- Replaced vanilla-block projectile materials with dedicated Boxhead projectile textures.
- Rebuilt title-screen CREATE/CONTINUE icons at 64x64 and upgraded the pack icon.

LOGIC / FEEDBACK PASS
- Added one-second live HUD refresh: money, current wave, living infected and kills.
- Added weapon-specific impact particles/sounds after confirmed hit detection without changing damage amounts or selectors.
- Added infected death particles/sounds without changing kill rewards.
- Added wave-start and wave-clear audio/particle feedback without changing wave budgets or progression.
- Added successful-spawn visual/audio cues after the original spawn checks succeed.

NO JAVA CHANGES.
